Answer:
$15
Step-by-step 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
