Answer 1

184/x = 115/100
184*100=18400
18400=115x
18400/115=160
x=160

Answer 2

$160

Explanation:

115% = $184

100% = X

let X be the original salary

(X is unknown)

115% = $184

100% = X

cross mutiply

115 x X = 100 x 184

115X = 18400

X = 18400 divided by 115

X = $160

therefore,Mr Black's original salary before increased by 15% was $160
