One person from your team must balance on one foot with their eyes closed. If this person loses balance before the problem is solved, you receive zero points.

Here's the problem:

Michael scores a 95, 87, 85, 93, and a 94 on his first 5 math tests. If he wants a 90 average, what must he score on the final math test?

Add the five past test scores and you get 454. Then set up an algebraic equation where you add 454 to x, which is the final test score, and divide by six, because you want the average for 6 tests now. You make this equation equal to 90 because that is the average Michael wants and solve for x:

(454+x)÷6=90

454+x=540

x=86

Your team must do a total of 30 pushups before attempting to answer the following problem:

Greg is trying to fill a 16 oz. bottle with water. If Greg fills the bottle at 1 oz per second and the bottle leaks .2 oz per second, how long would it take for Greg to fill the bottle?

Correct answer:

20 seconds

Explanation:

You first find the rate at which the bottle is being filled at, which is  

1oz.−0.2oz=0.8oz.

Then you divide the entire bottle, which is 16oz. by the rate of .8oz, and you get 20 seconds.
