If the aquarium had 6 fewer penguins, and the remaining penguins were fed their usual portions, the aquarium would feed its penguins a total of 15 pounds less fish each day. If each of the penguins receives the same amount of fish each day, how many penguins does the aquarium have?
A 32
B 38
C 45
D 74
E 80
6 fewer penguins = 15 fewer pounds of fish, implying the following proportion:
(6 penguins)/(15 pounds of fish) = (x penguins)/(80 pounds of fish)
2/5 = x/80
5x = 160
x = 32.
The correct answer is
A.
