Earl spent $1540 on a sofa. He spent 1/5 of his remaining money on a vase. He then had 1/4 of his orignal sum of money left. How much money did Earl have at first?
x = original amount
x - 1540 amount after sofa purchase
spending 1/5 means 4/5 is left
4/5 ( x - 1540) and this equals 1/4x
4/5 (x - 1540) = 1/4 x Now, just solve for 'x' ......
