Marcus spent $36 on some plates and 3/4 of his remaining money on some cups. If he had 1/6 of his original sum of money left, how much money did he have at first?
36 = 1/4x = 144 on some cups
36 = 1/6x = 216 his original money
216 - 144 = 72 right now
$72 + $36 = $108
$108 he have at first
x = origianl amount
(x -36) 1/4 = 1/6 x ( spending 3/4 leaves 1/4)
x = 108 dollars oriinally
