Malcom has $1043 in bills in the following denominations: hundreds,fifties,twenties,fives,and ones. He has three times as many fifties as hundreds;twelve times as many twenties as hundreds;and four times as many ones as hundreds. He has nine more fives than hundreds. How many of each denomination of bills does he have?
H, F , T , V, and O
100H + 50F + 20T + 5V+ O = 1043
3H = F
12H = T
4H = O
V = H + 9
sub in to give:
100H + 50(3H) + 20(12H) + 5(H + 9) + 4H = 1043
100H + 150H + 240H + 5H + 45 + 4H = 1043
499H+ 45 = 1043
499H = 998
H = 2
thus 2 hundreds ==> $200
6 fifties ==> $300
24 twenties ==> $480
8 ones ==> $8
11 fives ==> $55
total: $1043 checks
