She received a $5 bills and $10 bills. The number of $10 bills was 10 less than three times the number of $5 bills. How many bills of each type did Mrs. Carey receive? Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Let's call the number of $5 and $10 bills, x and y.
Thus we have
y = 3x - 10 and their value
5x + 10y = 600
Now substitute
5x + 10(3x - 10) = 600
5x + 30x - 100 = 600
35x = 700
x = 20 $5 bills
y = 3(20) - 10 = 50 $10 bills
