Steve puts only dimes and quarters into his piggy bank. Right now he has five more dimes than quarters there, and they make exac
tly $74! How many quarters and how many dimes are there in Steve’s piggy bank?
1 answer:
X - quarters, x+5 - dimes.
$74=7400 cents
Then
(25x+10(x+5))=(25x+10x+50)=(35x+50) cents.
35x+50=7400
35x=7400-50
35x=7350
x=7350/35
x=210 quarters
x+5=210+5=215 dimes
210 quarters and 215 dimes
