Question 1189253
<br>
The solution from the other tutor contains errors, which I know she will fix....<br>
The value of the quarters is $60; at 4 quarters per dollar, the number of quarters is 60*4 = 240.<br>
The percentage of coins that are quarters is 100%-30%-15%-25% = 30%.<br>
That tells us that the number of pennies is the same as the number of quarters (30% of the total), and the number of nickels is half of that (15% of the total).  So there are 240 pennies and 120 nickels.<br>
There are many ways to find the number of dimes; I personally would see that 25% is 5/6 of 30%, so the number of dimes is 5/6 of 240, which is 200.<br>
So there are
240 pennies
120 nickels
200 dimes
240 quarters<br>
for a total value of $2.40+$6.00+$20.00+$60.00 = $88.40<br>
