To solve this problem you must apply the proccedure shown below:

1. The halving and doubling is a multiplication strategy which is very useful to simplify products.

2. You have the following multiplication given in the problem above:

3. Then, by applying this strategy, you have that the double of 50 is 100 and the half of 28 is 14. Therefore, when you multiply them, you obtain:

Therefore, the answer is: .

true

step-by-step explanation:

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.
