At the beginning of the week, Naveen has 87 trading cards. On Monday, he gets 9 more. On Tuesday, he gives 16 away. On Wednesday, he is given 3 by a friend. On Thursday, he sells all of his cards to a collector. The collector pays him a rate of c for every card that Naveen has. If Naveen earns 124 point 5 0 dollars from the sale, what is c , the rate that the collector pays for each card?
Naveen has 87 + 9 − 16 + 3 = 83 cards when he sells them. Divide the $124.50 total payment by 83 cards: $124.50 ÷ 83 = $1.50 per card. So the rate is 1.50 dollars, choice C.
