Question

Carol has 7 rolls of pennies containing 50 coins each, 11 rolls of nickels containing 40 coins each, 3 rolls of dimes containing 50 coins each and 12 rolls of quarters containing 40 coins each. How much money does she have?

Answer 1

I believe the answer is 160.50 because you would

Multiply 7(50) in pennies=$3.50 since 100 pennies equal 1 dollar

Multiply 11(40) nickeles=440/20=$22.00 since it takes 20 nickels to equal 1 dollar.

Multiply 3(50) in dimes=150/10=$15 since it takes 10 dimes to equal 1 dollar

Multiply 12(40) in quarters= 480/4=$120 since it takes 4 quarters to equal 1 dollar

Add $3.50+$22+$15+$120

=$160.50

I hope this helps you!

Answer 2

So what you have to do is multiply 7 times 50 multiply 11 times 40 multiply 3 times 50 multiplied 12×40 and you get 1420
