Problem Analysis

We are given that there are 5 boxes of cookies weighing a total of 45 kg, and each box of candy weighs 7 kg more than a box of cookies. We need to find the weight of 3 boxes of candy.

Solution

Let's start by finding the weight of one box of cookies. We are given that 5 boxes of cookies weigh 45 kg, so the weight of one box of cookies can be found by dividing the total weight by the number of boxes: 45 kg / 5 = 9 kg per box.

Next, we need to find the weight of one box of candy. We are told that each box of candy weighs 7 kg more than a box of cookies. Since one box of cookies weighs 9 kg, one box of candy weighs 9 kg + 7 kg = 16 kg.

Finally, we can find the weight of 3 boxes of candy by multiplying the weight of one box of candy by 3: 16 kg * 3 = 48 kg.

Therefore, 3 boxes of candy weigh 48 kg.

Answer: 3 boxes of candy weigh 48 kg.
