Question 1124283: Omar collected twice as many dollar bills as fives and one fewer ten than fives. If Omar collected $58, how many tens, fives, and ones did he get? Answer by ikleyn(52814) (Show Source):
Let F be the number of five-dollar bills,
Then the number of dollar bills is 2F
and the number of ten-dollar bills is (F-1).
The "money" equation is
5F + 2F + 10*(F-1) = 58,
Simplify and solve for F:
17F = 68
F = 68/17 = 4.
Answer. 4 five-dollar bills; 2*4 = 8 dollar-bills and 4-1 = 3 ten-dollars bills.
Check. 4*5 + 8*1 + 3*10 = 58 dollars. ! Correct !
