If he had a total of 60 coins, how many of them were quarters?What was the total dollar value of these coins?

Question

Zachary had 4 times the number of quarters (25 cents) in his bag than dimes (10 cents).

Answer 1

Let the number of dimes = x

Let the number of quarters = 4x

 

Set the equation based on the problem description.

 

x + 4x = 60

 

 

Solve for x.

 

5x = 60

 

x = 12

 

 

Substituting this value of x into the variables,

 

He has 12 dimes and 48 quarters.

 

 

The total dollar value = $0.10(12) + $0.25(48)
