Question

Scott has a jar of quarters and dimes. If there is $4.15 in the jar, and there are 4 dimes, how many quarters are in the jar

Answer 1

Dimes are $0.10
4 dimes = 4(.10)=$0.40
$4.15 - $0.40 = $3.75

Answer 2

There are $3.75 worth of quarters.
A quarter is $0.25.
Therefore,
$0.25 x = $3.75
Divide both sides by $0.25 and what do you get?

Answer 3

You get 15.
There are 15 quarters in the jar.
