Question

a student has some $1 and $5 bills in his wallet. he has a total of 15 bills that are worth $47. how much of each type of bill does he have

Answer 1

8 $5 bills and 7 $1 bills.

Explanation:

The first thing that i tried was seeing how much $5 bills went into 47 which is 9 with 2 remainder. But if u added two $1 bills then there would only be 11 bills in total. So what i did was remove one $5 bill which equals 42, then i add five $1 bills which equals 15 bills in total. 8 $5 bills and 7 $1 bills.
