A class used vans and buses to go on a field trip. They used 8 vehicles to go on the trip. Each van holds 11 students and each bus holds 35 students. If 160 students went on the trip, then how many of each type of vehicle did the class use?

So important things to know...

What are they asking

To find how many of EACH vehicle does the class need to use.

35 x 3 = 105

160 - 105 = 55

55 / 11 = 5

3 Buses were used

5 vans were used

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
