Hi Addison;
We need a multiple of 0.25 that results in 6.25. This is because...
6.556.25=0.30
25 quarters=6.25
3 dimes=0.30
total=$6.55
Of course, there are other solutions, such as the quantity of quarters rendering a total of $5.75. As long as the total value of quarters is $X.25 or $X.75, this will work with any corresponding quantity of dimes.
