Question

The Nelson family lives in a town where there is a swim club. At the beginning of the summer, they pay a membership fee of $40 and then $5 for each visit to the pool. Their friends, the Jacksons, live in the next town over and also pay swim club fees, which are expressed in the equation y=10x+15. What is the difference between what the Nelson family pays and what the Jackson family pays if each family visits the pool 8 times during the summer? Group of answer choices $15 $230 $160 $5

Answer 1

$15

Explanation:

Nelson family:

y = 5x + 40

Jackson family:

y = 10x + 15

Where,

y = Amount paid

x = number of visits

if each family visits the pool 8 times during the summer?

Nelson family:

y = 5x + 40

= 5(8) + 40

= 40 + 40

= 80

y = $80

Jackson family:

y = 10x + 15

= 10(8) + 15

= 80 + 15

= 95

y = $95

What is the difference between what the Nelson family pays and what the Jackson family

Difference = $95 - $80

= $15
