When Harriett vacuumed the sofa and chair she found 10 quarters, 3 dimes, 3 nickels, and 5 pennies.  How much money did Harriett find?
She found 10 quarters that are $0.25 each so she found 10*.25 = $<<10*.25=2.50>>2.50
She found 3 dimes that are $0.10 each so she found 3*.10 = $<<3*.10=0.30>>0.30
She found 3 nickels that are $0.05 each so she found 3*.05 = $<<3*.05=0.15>>0.15
She found 5 pennies that are $0.01 each so she found 5*.01 = $<<5*.01=0.05>>0.05
All total she found 2.50+.30+.15+.05 = $3.00 in change
