Amount of dog food required for 24 dogs for 7 days = 10*24*7 ounces;
Amount of dog food in each case = 30*8 ounces

Number of cases required = 10*24*7/30*8 = 7 cases

The correct answer: C

Hope this helps!

Since each dog requires 10 ounces of dog food per day, 24 dogs require 10 x 24 = 240 ounces of dog food per day and 240 x 7 = 1680 ounces of dog food for the 7 days.

Since each case of dog food has 30 cans and each can has 8 ounces of dog food, a case has 30 x 8 = 240 ounces of dog food.

Therefore, 1680/240 = 7 cases of dog food are needed to feed 24 dogs for 7 days.

Answer: C
