reinhard10158

Step-by-step explanation:

1 system in 2 3/4 hours = (8+3)/4 = 11/4 hours

how many in 40 hours ?

well as many systems as times 11/4 fit into 40 :

40 / 11/4 = 40/1 / 11/4 = 40×4 / 11×1 = 160/11 =

= 14.54545454... systems

since the question is for completed systems (and parts of a system is not completed, we have to round it down to the nearest whole number : 14.

she can complete 14 systems in 40 hours.
