Question

21. An automotive technician is paid by the job, or flat rate, so that his hours will vary on a daily basis.

Answer 1

On a particular day, our technician completed six jobs and accumulated the following hours:

`1.5,0.6,0.4,1.0,2.2,1.5`

The total number of hours points directly to an addition. The total number of hours he accumulated (T) was:

`T=1.5+0.6+0.4+1.0+2.2+1.5=7.2`

Our desired answer is 7.2.
