Word Problem

[Moy12]

A pack of 10 baseball cards costs $3. A pack of 12 basketball cards costs $3. If Karim spends $15 on packs of one type of card, then at most how many more basketball cards than baseball cards could he purchase?

The possible choices are:

a) 3
b) 5
c) 7
d) 9
e) 10

I don't understand, if Karim is only buying one type of card, then he could purchase $15 worth of basketball cards. That's $15 / $3 * 12 = 60 more basketball cards than baseball cards. Can somebody help me understand this problem?

number of basketball cards $15 / $3 * 12 = 60
number of baseball cards $15 / $3 * 10 = 50
how many more basketball cards than baseball cards 60-50=10

the answer is e
