Experts' GlobalThis question is a bit tricky, because if you use cost per person, you have one more step: the cost of the item.

When 25 students pay for an item, it costs $16 more per person than it does when 30 students buy the same article.

Let cost per person = x

30x = 25(x + 16)

30x = 25x + 400

5x = 400

x = 80

So the cost of the article is

(30)($80) = $2,400

Check for accuracy:

Cost

per person when 25 buy?

Cost per person = (x + 16) = (80 + 16)= $96

Total cost? ($96)(25) = $2,400

A match. Correct.

Answer E
