Kate is going to buy either 1, 2, 3, or 4 pens. The cost of buying n pens is given by the function F(n)=1.25n, where F(n)=cost in dollars.
Which best describes the range of Fin) in this situation?

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
