a grand total of $8.20, with the same number of pennies, nickels, dimes, and quarters.
How many of each coin were there?
:
Let x = no. of each coin
:
.01x + .05x + .10x + .25x = 8.20
.41x = 8.20
x = 8.20%2F.41
x = 20 of each coin
:
:
See if that is true
.01(20) + .05(20) + .10(20) + .25(20) =
.20 + 1.00 + 2.00 + 5.00 = 8.20
