10(x/2 + 8) = 11, expand
10x/2 + 80 = 11
5x/2 = 11-80= -69
5x = -138
x = - 138/5
54/2 = 27
27-8 = 19
27 + 8 = 35
19+35 = 54
35 - 19 = 16
Answer:
$33600
Step-by-step explanation:
Let x = original car price
Since it is a 25% profit that means we multiply x by 1.25
1.25x = 42000
Divide both sides by 1.25
1.25x/1.25 = 42000/1.25
x = 33600
