Answer:
The expression represents Ann's membership cost as a function of how many times she brings John along. For t = 5 the cost is 275, for t = 10, the cost is 250 and for t = 20 the cost is 200.
Step-by-step explanation:
The expression "300 - 5*t" represents the cost of Ann's membership plan on the local gym, where "t" is the number of visits John pays Ann. This means that the more times John goes to the gym with Ann, the less is her cost to pay the membership.
For t = 5:

For t = 10:

For t = 20:

The second day, she sold more.

And 0.78 < 0.85
So the second day she sold more.
