Jaeden · Answer 1

Let x = original savings

(x-1,600) - 2/5 (x-1,600) = 1/3x

(x-1,600) - 2/5 + 640 = 1/3x

(3/5) x - 960 = 1/3x

(3/5) x - (1/3) x = 960

(4/15) x = 960

(15/4) (4/15) x = (15/4) 960

x = 15 * 240 (960/4 = 240)

x = $3,600 is his original savings

Check:

$3,600 - 1,600 = 2,000

(2/5) ($2,000) = $800

2,000 - 800 = 1,200 left over
