You have a bunch of quarters and dimes but you don't know how many. You do know that the toal comes out to be $14.85. You also know that there are 2 times as many dimes as there are quarters. How many of each do you have?

Well the equation would be (.25x + .2x = 14.85)
Ok awesome! Where do I go from there?
Multiply both sides by 100 to get rid of the decimals
you should get 45x=1485
x= 33

What now?
Well, then you use the x value to determine the number of coins
So, 33 quarters and 66 dimes
since there is twice as many dimes
