Question

Working together, Mary and Trevon can

inflate twenty balloons in 7.34 minutes.
Had he done it alone it would have taken
Trevon 14.1 minutes. How long would it
take Mary to do it alone?

Answer 1

20 balloons in 7.34 minutes? lets do the math!
`(20)/(7.34\\)` = 2.73 balloons a minute.

If Trevon took 14.1 minutes, lets do the math,
`(20)/(14.1)` = 1.42 balloons a minute, now if we take 2.73, subtract 1.42 from 2.73. 2.73 - 1.42, we get, Drum roll please...................... 1.31 !!! So, with that fact, we get 1.31, so that means Mary would have to blow 1.31 balloons a minute WITH Trevon, now some more math. we take the amount Mary did, 1.31, and the amount of time it took for both, 7.34, we get this problem, 1.31 x 7.34 which equals (yes I'm doing it again) DRUM ROLL PLEASEEEE....................... 9.60!!!!!!!!

So, in the end, the answer is 9.60
