I HAVE $11.60, all dimes and quarters, in my pocket. I have 32 more dimes than quarters. how many dimes, and how many quarters do i have?
Let d = dimes and q = quarters.
We have two equations:
dimes (d) = 56 and quarters (q) = 24
Check our work:
56 - 24 = 32
0.10(56) + 0.25(24) = $5.60 + $6.00 = $11.60
Let d = dimes and q = quarters.
We have two equations:
- 0.10d + 0.25q = 11.60
- d - q = 32
dimes (d) = 56 and quarters (q) = 24
Check our work:
56 - 24 = 32
0.10(56) + 0.25(24) = $5.60 + $6.00 = $11.60
