What is the answer to my math problem from my school for homework today?

Know that there are 16 ounces in one pound.

To get the total amount of food served to all small-sized dogs, multiply a single serving amount (12.5 ounces) by the total amount of small-sized dogs (12).

12.5 × 12 = 150

Collectively, the small-sized dogs are served 150 ounces of dog food a day.

To find the total amount of dog food served to the medium-sized dogs, multiply the amount of one serving (18 ounces) by the total amount of medium-sized dogs (5).

18 × 5 = 90

Altogether, the medium-sized dogs are served 90 ounces of dog food daily.

Add those values together to get the amount of dog food served to both small- and medium-sized dogs in a day.

150 + 90 = 240

The animal shelter serves 240 ounces of dog food to small- and medium-sized dogs every day. But recall we need the answer in pounds. Remember there are 16 ounces in one pound, so if we divide our answer in ounces by 16, we'll have the same answer in pounds.

240 ÷ 16 = 15

The shelter serves 15 pounds of dry food in one day.
