Wayne's savings to Stef's savings were in the ratio 5 : 6. After spending $28 each, the ratio became 1 : 4.
(a) Find Wayne's savings before he spent $28.
(b) Find Stef's savings after she spent $28.
Wayne = (5/6)S.....so....
(5/6)S - 28 1
___________ = ____ cross-multiply
S - 28 4
4 ] (5/6)S - 28 ] = S -28
(10/3)S - 112 = S - 28
(10/3)S - S = 112 - 28
(7/3)S = 84
S = (84)(3/7) = $36 = Stef's savings
Wayne = (5/6)S = (5/6)(36) = $30 = Wayne's savings
