Answer:
$96.15
Step-by-step explanation:
Given data
markup = 30%
cost price= $125
let the cost price before markup be x
125-30/100*x= x
125-0.3x= x
125= x+0.3x
125= 1.3x
divide both sides by 1.3
x= 125/1.3
x= $96.15
Hence the price before markup is $96.15

Answer:
A). 15
B). -1.2
Step-by-step explanation:
A). [10(x+3)]-20 = 160
10x+30-20 = 160
10x+10 = 160
10x = 160-10
10x = 150
x = 150/10
x = 15
B). 5{[4(8+(5x))]-9} = 85
5(32+20x+9) = 85
5(32+9+20x) = 85
5(41+20x) = 85
205+100x = 85
100x = 85-205
100x = -120
100x/100 = -120/100
x = -1.2
