7nadin3 [17]
The correct answer is D) Miguel:  d=23t+10, Gabby d=28t

We multiply the speed of each person by t, the amount of time.  This is where the 23t in Miguel's equation and the 28t in Gabby's equation come from.  The starting point is added to this, which leads to 23t+10 and 28t+0 or 28t.

The number of boys that study French = 2/3 x 36 = 24

The numbber of boys that study German = 36 - 24 = 12

The number of girls that study French = 40 - 24 = 16

The number of girls that study German = 24 - 16 = 8
