a) Wayne's savings before he spent $28 is $30
b) Stef's savings after she spent $28 is $8
<u>Step-by-step explanation</u>:
step 1 :
let,
Wayne's savings = 5x
Stef's savings = 6x
step 2 :
After spending $28 each of them, The ratio becomes 1/4.
⇒ (28 - 5x) / (28 - 6x) = 1/4
⇒ 4(28 - 5x) = 1 (28 - 6x)
⇒ 112 - 20x = 28 - 6x
⇒ 112 - 28 = 20x - 6x
⇒ 84 = 14 x
x = 84/4 = 6
step 3 :
a) Wayne's savings before he spent $28 = 5x
substitute x=6,
Wayne's savings = 5(6) = $30
step 4 :
b) Stef's savings after she spent $28 = Total savings - $28
= 6x - 28
= 6(6) - 28
∴ Stef's savings after she spent $28 = 36 - 28 =$8
