Problem: a team of workers took 74.7 hours to complete the project. A smaller team of workers will complete the same task, but it will take them 1.15 times as long as it took the first team.

Solution: The small group takes the following amount of time to do the same task as the other group (first group):

`t\text{ = 1.15 x 74.7 hours = 85.905}`

So for A, B, and D, they are all false. but C is true.
