Question #N57
A store sells two types of cookies: chocolate chip and peanut butter. The store sells 3 chocolate chip cookies for every 2 peanut butter cookies. If the store sells 45 chocolate chip cookies in a day, how many peanut butter cookies do they sell in a day?
A. 15
B. 22.5
C. 30
D. 67.5
Correct Answer is: C
The ratio of chocolate chip cookies to peanut butter cookies is 3:2. Since the store sells 45 chocolate chip cookies, which is 3 times the value of the ratio, the store must sell 2 times that value in peanut butter cookies, or 30 peanut butter cookies.
