Answer:
The German shepherd eats 14 × 15 = 210 ounces per week.
Step-by-step explanation:
Jo has a gerbil and a German Shepherd. The German Shepherd eats 14 times as much as the gerbil. Altogether they eat 225 ounces of dry food per week.
let gerbil eat a ounces of food
Gerbil eats = a
shepherd eats = 14 × a
Altogether they ate 225 ounces per week , The expression can be written as
a + 14 × a = 225
a + 14a = 225
15a = 225
divide both sides by 15
a = 225/15
a = 15
The German shepherd eats 14 × 15 = 210 ounces per week.
