Question

Juan bought thirty books from a book dealer for $2.00 each, as

a promotion the dealer gave him five free copies. Juan then sold
all the books he got from the dealer for $5.00 each. What was
the profit Juan made?

Answer 1

Answer: $115

Explanation:

Since Juan bought 30 books for $2 each, the amount of money he spent was $60. He received 5 free copies, so that makes 35 books total.

Then, Juan sold each copy for $5, which means that the total money he earned is $5*35 = $175

Since he earned $175 and spent $60, his total profit is 175-60 = 115

Answer: $115
