Question

Can someone please tell me if I did this correct?
Your piggy bank has a total of 46 coins in it; some are dimes and some are quarters. If you have a total of $7.00, how many quarters and how many dimes do you have?

A quarter is valued at 25 cents each and the dimes are valued at 10 cents each. If the 46 coins have a total value of $7.00 then:

Number of quarters = x, and the balance is (46 - x), this will be the dimes in coins.

So the equation will be 25(x) + 10 (46 - x) = 700
25x + 460 - 10x = 700
15x = 240
x = 16

So the answer is that there will be 16 quarters and 30 dimes
