Question

A 10 cent coin is worth $0. 10. How many 10 cent coins are there in $4. 50

Answer 1

Let “d” represent “Dime,” since dimes are valued at $.10.

$.10•d=$4.50

We want to find how many dimes “d” there are to add up to $4.50.

Solve for “d:”

Divide both sides by .10

.10•d/.10=4.50/.10

d=45

Let’s check our answer:

.10(45)=4.5

4.5=4.5

Answer: 45 ten cent coins (dimes).
