Question

Carmelo is selling his hockey and baseball card collection. Hockey cards, x, sell for $0.03 and baseball cards, y, sell for $0.05. The number of hockey cards Carmelo sells is at least six times the number of baseball cards he sells. He has at most 525 cards to sell.

What is the maximum revenue he can make?



$15.75

$17.25

$26.25

$28.50

Answer 1

x= 6y

x + y = 525

solving these two equations

6y+y = 525

y = 75

x = 6*75=450

Total revenue = 450 * .03+ 75 * .05

= 17.25

THe answer is B. $17.25

Hope this helps!
