I'm not sure how to set this problem up and would like to see how it's done. Thanks!

Sometimes it is easiest to write the words of the problem using math symbols to find the equation you are being asked to solve:

5A = 2B + $6400 and **4A = 3B + $2600**

You need to use one equation and get one variable alone. I chose the one in **
bold**.

4A = 3B + $2600 (divide both sides by 4)

4 4

A = 3/4 B + $650 (Now you have solved for A. Use this in the other equation for A.)

5(3/4 B + $650) = 2B + $6400 (You must multiply A by 5 before you continue.)

15/4 B + $3250 = 2B + $6400 ( Solve for B by moving all B's to one side. Also, 15/4 = 3 3/4)

-2B -2B

(3 3/4 B + $3250 = 2B + $6400)

-2B -2B

1 3/4 B + $3250 = $6400

-$3250 -$3250

1 3/4 B = $3150

B = $1800 (Enter this into A = 3/4 B + $650)

A = 3/4 ($1800) + $650

A= $2000
