The Kennel house keeps 3 German Shepherds and 2 Bulldogs. If a German Shepherd consumes 5 kilograms of dog food and a bulldog consumes 3 kilograms of dog food per day. How many kilograms of dog food will they need in a week?
The German Shepherds consume 3 x 5 = <<3*5=15>>15 kilograms of dog food per day.
The Bulldogs consume 2 x 3 = <<2*3=6>>6 kilograms of dog food per day.
The dogs can consume a total of 15 + 6 = <<15+6=21>>21 kilograms of dog food per day.
Therefore, they need 21 x 7 = <<21*7=147>>147 kilograms of dog food in a week.
