Question

A safe contains $1895 in $1, $5, $10, and $20 bills. The number of $1 bills is three more than twice the number of $20 bills. The number of $5 bills is three more than five times the number of $20 bills. The number of $10 bills is five more than four times the number of $20 bills. How many bills of each type are there?

Answer 1

W =3 + 2T

F = 3+5T

E = 5+4T

W+5F+10E +20T = 1895

3 + 2T +5(3+5T) +10(5+4T) + 20T = 1895

2T+3 +15 +25T +50 + 40T + 20T = 1895

87T = 1895 - 68 = 1827

T = 1827/87 = 21 Twenties

W = 3+2T = 45 Ones

F = 3+5T = 108 Fives

E = 5+4T = 89 Tens

45 + 5(108) +10(89) + 20(21)

= 45 +540 +890 + 420

= $1,895

45, 108, 89 and 21 ones, fives, tens and twenties
