Step-by-step explanation:
X-8=(2x-8)
x-7=2x-8
collect like terms
x-2x=-8+7
-x=-1
but we are looking for X not -x
so answer is 1
Hope this helped!
Answer for x
2x-1/2=
2x=1/2 multiply both sides with 2
4x=1
x=1/4

Answer:
108.3%
Step-by-step explanation:
The manufacturer spends $12,000 in buying the car parts and sells the car for $25,000
Selling price= $25,000
Cost price=$12,000
Gain= selling price-cost price
= 25000-12000
= $13000
The percentage profit can be calculated by applying the formular below
Profit= Gain/cost price×100/1
=13000/12000×100/1
=1.083×100
= 108.3%
Hence the percentage profit is 108.3%
