an envelope contains 20 bills in denominations of \$1,\$5,\$10, there are two times as many \$5 bills as there are\$10 bills. the total of the envelope is \$54. how many of each bill do i have

• Math -

let number of tens be x
then number of fives = 2x
number of ones = 20 - 3x

10x + 5(2x) + 1(20-3x) = 54

solve for x, sub back into my definitions

(should get 2 tens, 4 fives, and 14 ones)
