savior took a total of 124 quarters and dimes to trade in for cash at the bank he got exactly $25 back how many quarters did he have
Let Q be the number of quarters and D be the number of dimes.
1. Q + D = 124 (Total number of coins)
2. 0.25Q + 0.10D = 25 (Total value of coins)
From equation 1, we can write D = 124 - Q and substitute into equation 2:
0.25Q + 0.10(124 - Q) = 25
0.25Q + 12.4 - 0.10Q = 25
0.15Q = 12.6
Q = 84
Therefore, Savior had 84 quarters.
