You can put this solution on YOUR website!
$13.50 *(2/9) = $3,,$3/.50 = 6 coins
.
Remaining,,,13.50 -3 =10.50
.
$ 10.50 * (4/7) = $6,,$6/.25 = 24 coins
.
Remaining,13.5 -3 -6 = $ 4.50
.
$4.50 = x(.05) +x(.10) = x(.15),,,,x=30
.
That is 30 coins nickels and 30 coins dimes
.
Total coins is ( 6+24+30+30) = 90 coins
.
.
check 6 * .50 = $3,,,,24* .25 = $6,,,30*.05 =$1.50,,,30*.10=$3.00
.
(3+6+1.50+3) = $ 13.50,,,ok
