I'm so confused. i tried the first time got 50 some thing then 33 then 20.25. how do i do this?

Basically, you have to think: more bricks : more time

more workers : less time

2,400 bricks 6 workers takes 18 hours

You now have to solve for 4,500 blocks and 10 workers

4,500 / 2,400 = 1.875 (times greater)

10 / 6 = 1.666666666 (times less)

So, we get 18 hours, multiply it by 1.875 and divide it by 1.666666666

which equals 20.25 hours

So, it seems you were correct on your third try.

Step-by-step explanation:

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i
