Roth · Answer 1

The number of coins you have in this equation is

123.50 that's the amount

Armando · Answer 2

Let Q = quarters and D = dimes

There are a total of 1202 coins, so we have to add the quarters and dimes together to get this.

Q + D = 1202

Quarters have a value of 25 cents or 0.25, dimes have a value of 10 cents or 0.10. The combination of the amount of quarters and their respective value and the amount of dimes and their respective value equate to $123.50.

0.25Q + 0.10D = 123.50

Put the two equations together. Your system of equations is:

Q + D = 1202

0.25Q + 0.10D = 123.50
