7. Alex makes $30,000 a year at his job
and gets $2,500 a year raise every year.
Sydney makes $40,000 a year and gets a
$2,000 raise every year. How many years
will it take for them to make the same
salary?

Answers

Answer:

It will take them 20 years to make the same salary

Step-by-step explanation:

Let us solve the question

Assume that they will have the same salary after x years

∵ Alex makes $30,000 a year at his job

∵ He gets a $2,500 a year raise every year

∵ He will work x years

→ That means his salary is the sum of a fixed amount and the raise times x

∴ His salary = 30000 + 2500(x) ⇒ (1)

∵ Sydney makes $40,000 a year

∵  He gets a $2,000 raise every year

∵ He will work x years

→ That means his salary is the sum of a fixed amount and the raise times x

∴ His salary = 40000 + 2000(x) ⇒ (2)

∵ They will make the same salary after x years

→ Equate (1) and (2)

30000 + 2500x = 40000 + 2000 x

→ Subtract 30000 from both sides

∴ 2500x = 2000x + 10000

→ Subtract 2000x from both sides

∴ 500x = 10000

→ Divide both sides by 500

x = 20

It will take them 20 years to make the same salary

Dylan's mother gets a restaurant bill for $25. She has a coupon for 15% off. After the discount is applied, she adds 20% tip for the server. What is the total that Dylan's mom will pay at the restaurant?

Answers

Given:

Amount of bill = $25

Coupon = 15% off

Tip = 20% after discount is applied.

To find:

The total that Dylan's mom will pay at the restaurant.

Solution:

We have,

Amount of bill = $25

Discount = 15%

Amount after discount = 25 - 15% of 25

                             [tex]=25-\dfrac{15}{100}\times 25[/tex]

                             [tex]=25-3.75[/tex]

                             [tex]=21.25[/tex]

So, amount after discount is $21.25.

Tip = 20%

Total Amount = Amount after discount + Tip

[tex]\text{Total Amount}=21.25+\dfrac{20}{100}\times 21.25[/tex]

[tex]\text{Total Amount}=21.25+4.25[/tex]

[tex]\text{Total Amount}=25.5[/tex]

Therefore, Dylan's mom will pay total $25.5 at the restaurant.

The table shows the amount of money Tyler earns for mowing lawns. Is the
relationship a proportional relationship? Complete the explanation.

Answers

Answer:

The constant of variation 'k' is NOT constant.

Therefore, we conclude that Taylor did not charge a constant rate. The rates are not equal because his rate changed.

Step-by-step explanation:

Given the table

Number of Lawns         1           2            3              4

Amount Earned ($)      16         32          54            72

We know that when y varies directly with x, we get the equation

y ∝ x

y = kx

k = y/x

where 'k' is called the constant of proportionality.

In our case, the 'Amount earned ($) ' is represented by 'y', and the 'Number of Lawns' is represented by 'x'.

Let us check the constant of proportionality using the equation

k = y/x

k = 16/1 = 16

k = 32/2 = 16

k = 54/3 = 18

k = 72/4 = 18

It is clear that that the constant of variation 'k' is NOT constant.

Therefore, we conclude that Taylor did not charge a constant rate. The rates are not equal because his rate changed.

(7x + 34)
(10x - 23)

Answers

not sure what’s your question , like the topic but I’ll help
Simplifying
7x + 34 = 10x + -23

Reorder the terms:
34 + 7x = 10x + -23

Reorder the terms:
34 + 7x = -23 + 10x

Solving
34 + 7x = -23 + 10x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-10x' to each side of the equation.
34 + 7x + -10x = -23 + 10x + -10x

Combine like terms: 7x + -10x = -3x
34 + -3x = -23 + 10x + -10x

Combine like terms: 10x + -10x = 0
34 + -3x = -23 + 0
34 + -3x = -23

Add '-34' to each side of the equation.
34 + -34 + -3x = -23 + -34

Combine like terms: 34 + -34 = 0
0 + -3x = -23 + -34
-3x = -23 + -34

Combine like terms: -23 + -34 = -57
-3x = -57

Divide each side by '-3'.
x = 19

Simplifying
x = 19

Ron can buy seven candy bars for $4.41. What would be the cost of 2 candy bars?
a $8.82
b $0.63
c $1.26
d $1.15

Answers

The answer is C.

$4.41 divided by 7 is $0.63
$0.63 equals one candy bar
$0.63 times 2 = $1.26

$1.26 for 2 candy bars
The correct answer would be C. My reasoning behind this is because if Ron has seven bars, you would divide the price, the price being 4.41. After dividing the price by seven, you would get the answer of 0.63, that’s the price of one. If you add 0.63+0.63 you would get 1.26, the price for two bars.



EXAMPLE:

4.41*7= 0.63

0.63+0.63=1.26

Total: $1.26

Answer: Yes

Step-by-step explanation:

From the question, we are informed that a survey was conducted of 880 college students attending the same university and that they were offered a list of 10 different internet service providers and were asked to select the one they prefer.

Basee on this information, if everyone selected equal numbers, each service provider will get (880 / 10 = 88 students). In this case, if someone has 89 votes, this means that another person will get 87 votes while the remaining 8 service providers gets 88 students each. Therefore, the device provider with 89 votes can come out on top.
