Question 595557
Since our values are stated in dollars we will use the decimal equivalents for the quarters (0.25$) and nickels (0.05$), If you don't like working with decimals, you can leave everything at the "penny" level as it allows you to work with integer numbers.  Your equation is a good start, but it fails to include the dollar values for a nickel and a quarter.

The value of x quarters is 0.25*x
The value of 2x nickels is 0.05*2*x
The value of the dimes is $15.30.

If we add all that up, the total dollar amount is $74.80.

So your equation would be:

0.25x + 0.05*(2x) + 15.30 = 74.80.

Since you only asked for the equation. I will let you go through the process of solving it.  I can tell you that the correct answers are 170 quarters and 340 nickels.
