E Question 4 (Click TOT IST)
Paris buys 18 kilograms of dog food for her wolf hound that costs $114.30.
The dog food can be purchased in 1 kilogram bags.
How much does 11 kilograms of the same dog food cost?

11 kilograms of the same dog food costs $69.85.

Step-by-step explanation:

Step 1:

Paris buys 18 kg of dog food for $114.30. The food can be purchased in 1 kg bags.

If she bought the 18 kg of dog food with 1 kg bags, she would have had to buy 18 such bags.

So we need to calculate the cost of a 1 kg bag.

If 18 bags cost $114.30 we divide it by 18 to calculate the cost of 1kg.

The cost of a 1 kg bad

So a 1 kg bag of dog food costs $6.35.

Step 2:

To calculate the cost of 11 kg of the same dog food, we multiply the cost of a single bag with the number of bags.

If she were to buy the 11 kg through 1 kg bags, she would need to buy 11 such bags.

The cost of 11 kg of dog food  

So 11 kg of dog food would cost $69.85.
