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?

20 balloons in 7.34 minutes? lets do the math! = 2.73 balloons a minute.

If Trevon took 14.1 minutes, lets do the math, = 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, in the end, the answer is 9.60
