Stan buys a 1966 Mustang with the intention of repairing, restoring and selling it. He anticipates that it will cost him $10,000 to purchase, repair and restore the car, and that he can sell the finished car for $13,000. When he has spent a total of $10,000 on the project, he discovers that he needs to replace the engine. It will cost Stan $4,000 to replace the engine. He can sell the car without the new engine for $9,000.What should he do?

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
