two friends sold many pieces of furniture and made $1720 during the garage sale. They had fourteen more $10 bills than $50 bills. They had 4 more than two times as many $20 bills as $50 bills. How many of each denomination did they have?

Answer 1

number of fifties --- x
number of tens ---- x+14
number of twenties -- 2x+4

50x + 10(x+14) + 20(2x+4) = 1720

Solve for x, and all shall be revealed.

Answer 2

50x+10(x)+140+20(2x+4)=1720
50x+10x+140+40x+80=1720
100x+220=1720
100x=1720-220
x=1500/100
x=15

15 fifties
29 tens
34 twenties
