Question

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 $124.50 from the sale, what is c, the rate that the collector pays for each card?
$1.08
$1.50
$41.50
$83.00

Answer 1

For this world problem, just work along with each statement.

87 + 9 - 16 + 3

Now he sells them to a collector and Naveen earns $124.50. So to find the rate for each card, or $ earned per 1 card, just find $124.50 divided by the number of cards he sells. Then you'll find the rate c.
