Final answer:
The expression to calculate the number of calories in a package with m cookies and n crèmes per cookie is m * (x + (n * y)), where x is the number of calories in each cookie and y is the number of calories in each crème.
Step-by-step explanation:
To find the expression for the number of calories in a package with m cookies and n crèmes per cookie, we need to consider the number of calories in each cookie and multiply it by the total number of cookies and crèmes. Let's assume each cookie has x calories and each crème has y calories. The expression would be:
Expression = m * (x + (n * y))
For example, if each cookie has 100 calories and each crème has 50 calories, and there are 10 cookies and 2 crèmes in a package, the expression would be:
Expression = 10 * (100 + (2 * 50)) = 10 * (100 + 100) = 10 * 200 = 2000 calories.
