For bills gym membership, he pays $25 per month plus a one dollar charge per class he takes. Bills total for last month was $32. How many classes did he take?

7

Step-by-step explanation:

25$ Basic fee per month.

25 + 1 = 26 = 1 Class

26 + 1 = 27 = 2 Classes

27 + 1 = 28 = 3 Classes

28 + 1 = 29 = 4 Classes

29 + 1 = 30 = 5 Classes

30 + 1 = 31 = 6 Classes

31 + 1 = 32 = 7 Classes

or

32 - 25 = 7

So Bill took 7 classes

7 classes because $32 - $25 = 7 (where $25 is for one month, and the 7 is how much is left over of the total and 1 class = $1 dollar)
