A PIGGY CONTAINS $8.20 IN COINS. IF THERE ARE AN EQUAL NUMBER OF QUATERS,NICKELS,DIMES,AND PENNIES ,HOW MANY OF EACH DENOMINATION ARE THERE ?
:
Let x = no. of quarters, nickels, dimes and pennies
:
.01x + .05x + .10x + .25x = 8.20
.41x = 8.20
x = 8.20%2F.41
x = 20 each of each coin
:
:
Check this
.01(20) + .05(20) + .10(20) + .25(20) =
.20 + 1.00 + 2.00 + 5.00 = 8.20
