6. given the following equation y = 35x - 1600, write a real-life problem about a gym that could be modeled by this equation. remember to identify your variables.

Givens

The cost of one piece of new equipment = 400

The number of new items needed = 4

Cost of one month's use = 35 dollars.

Income from 1 month's use = y

The gym will be be down for 1 month. He has x members who each pay 35 dollars for the use of the gym for a month. What is the total amount (y), that he is "out" for the month.

y = 35x + 400*4.

ab will be equal to
