Final answer:
To find the number of calories in a 15-kg package of cheese, a proportional relation is used based on the calorie content of a smaller package, leading to the solution of 60,000 calories.
Step-by-step explanation:
The question involves a simple proportion calculation to determine how many calories are contained in a large 15-kg package of cheese, given that a small 0.5-kg package contains 2000 calories. To find the number of calories in the larger package, we can set up a proportional relation based on the weight and calorie content of the small package:
Calories in 0.5 kg : Weight of small package = Calories in 15 kg : Weight of large package
2000 calories : 0.5 kg = x calories : 15 kg
Cross-multiplying, we get:
0.5 kg * x calories = 2000 calories * 15 kg
Divide both sides by 0.5 kg to solve for x:
x = (2000 calories * 15 kg) / 0.5 kg
x = 60,000 calories
Thus, a large 15-kg package of cheese contains 60,000 calories.
