Greg has a dollar bill, quarters, and dimes. how many ways can he make $1.75?
One dollar, one quarter and 5 dimes
Since he always has the dollar bill, the problem then goes to how many ways can he make $.75 out of quarters and dimes. If both have to be used, it would only be 5 dimes and one quarter — one way. However, it could also be done with 3 quarters alone, giving you two ways.
He would have some quarters left over with the first alternative.
I think he has 7 ways to make $1.75 using dollars, half dollars, and.quarters
1. One dollar and 3 quarters
2. One dollar, 5 dimes and 1 quarter
3. 7 quarters
4. 10 dimes and 3 quarters
5. 15 dimes and 3 quarters
