Simple word problem causes dispute A company purchases 200 VCR units at a price of \$220 each. For each order of 200, there is a fee of \$25 added as well. 
If the company sells each VCR unit at a price marked up 30 percent, what is the profit per unit?
-First dispute was that no one buys VCRs anymore. Agreed! Let's look past this point . . .
Some students solved by doing the following;
200 units costs \$220 each with a \$25 fee, so: 
200 * 220 + 25
44000 + 25
44025 
That's the cost. Now the revenue, a 30% mark up of the cost price, times the number of units, so: 
(1.3 * 220) * 200
286 * 200
57200 
That's the total revenue. The total profit is the difference: 
57200 - 44025
13175 
And divide by the number of units to get the profit per unit: 
13175 / 200 = \$65.88 per unit (rounded to nearest penny)
Others solved this way;
Calculate the cost per unit as 220.125 - Because of the \$25 fee added. So, \$44025 / 200 = 220.125
220.125 * 1.3 = \$286.1625
\$286.1625 - \$220.125 = \$66.0375
To nearest penny, I calculate a profit of \$66.04
What is the true profit per unit?

This dispute is if the order fee applies per order or per VCR, and it seems from the wording that the per order fee must apply per order, not per VCR, so the second approach is correct.
