if $168.00 is the profit on a job, and this represents 8%of the contract price,what is the contract price?
Galina-37 [17]

We are told that $168.00 represents 8% of the contract price; therefore,we know that

original price *( 8/100) = $168.00

Now, writing out "original price" is a bit space-consuming; therefore, we will just rename it and say

original price = OP

Then, our equation above can be written as

OP\times\frac{8}{100}=168

We solve for OP (original price) by multiplying both sides by 100 and then dividing by 8. This gives us

OP=\frac{100}{8}\times168\textcolor{#FF7968}{\therefore OP=2100}\text{\textcolor{#FF7968}{.}}

Hence, the original contract price is $2100.
