Chase has 3 times as many dimes as quarters. The quarters have a total value of 6.60 dollars.  How many of each coin does he have?

Let the number of quarters = Q

Then, the number of dimes =3Q

 

0.25Q  +  0.10 * 3Q = 6.60, solve for Q

 

Q = 12 quarters

 

6.60 - [12 x 0.25] = 3.60 dollars, which are ALL in dimes.

 

[3.60 x 100] / 10 = 36 dimes.

Sorry, misread your question !!!.

 

If the quarters have a total value of 6.60, then:

6.60 / 0.25 =26.4 - ???!!!! 

Well, there is something wrong! Your quarters must have a value that is a multiple of 25. Right?

Could be 6.50? Or other amount?
