Mr. hoya brought 5 watermelons from his grocery store. the watermelons weighed 8.25 pounds, 9.25 pounds, 8.875 pounds, 9.625 pounds and 10.75 pounds. at the party, 153 people each ate a 0.25 pound serving of watermelon. was the amount of leftover watermelon less than, greater than, or equal to 8.5 pounds? explain how to solve the problem.

The first thing we must do for this case is to find the total weight of the watermelons.
 We have then:
 
 We now look for the amount of watermelons that people ate.
 We have then:
 
 Therefore, the amount of watermelon remaining is:
 
 We note that the amount of watermelon remaining is equal to 8.5 pounds.
 
 the amount of leftover watermelon is: equal to 8.5 pounds

The amount of leftover watermelon is equal to 8.5 pounds

Explanation:
1- getting the total weight of the watermelon:
The total weight of the watermelon will be the summation of the weights of the 5 watermelons he bought.
This means that:
Total weight = 8.25 + 9.25 + 8.875 + 9.625 + 10.75
Total weight = 46.75 pounds

2- getting the weight of the eaten watermelon:
We know that at the party, there were 153 people and each ate 0.25 of a pound of watermelon.
This means that:
amount eaten = 153 * 0.25
amount eaten = 38.25 pounds

3- getting the weight of the leftover:
weight of leftover = total weight - amount eaten
We have:
Total weight = 46.75 pounds
amount eaten = 38.25 pounds
Therefore:
weight of leftover = 46.75 - 38.25
weight of leftover = 8.5 pounds

Hope this helps :)
