Question

I need help with number 7 can someone explain how u get the answer?

Answer 1

5 months

Explanation:

Set up an inequality, using x to represent months.

(The 35 and 40 represent the cost per month, and you add the 100 and 75 just once because it's a one-time fee and not monthly)

35x + 100 < 40x + 75

Now solve for x.

5x > 25

x > 5

This means that the membership will be less expensive after 5 months.
