Question

1. Mindy’s high school class has a total of 150 students and they are planning a field trip. The school has
small buses and vans to transport all students. Each van can seat 8 students and each bus can seat 14
students. There are only 15 drivers, so the total number of vehicles that they can take must be 15. How
many of each vehicle will Mindy’s qass need to transport everyone?!
a. Write a system of equations to describe the situation.

Step-by-step explanation:

150 students        van holds 8 students         small bus holds 14 students

with only 15 drivers you can only have 15 vehicles

v  =  vans     b = buses

eq 1)        v +    b    =   15

eq 2)      8v +  14b  =  150

eq 1)       into          eq 2)                        the combined equations

v = 15 – b    —->   8v  +  14b  =  150   —->      8(15 – b) + 14b  =  150

8(15 – b) + 14b  =  150        solve for b

120 – 8b + 14b =  150        collect terms and subtract 120 from both sides

120 -120 + (14 – 6)b  = 150 -120

6b   =  30

b   =   30/6

b = 5

noe find the number of vans

v + b = 15

v  =  15 – b

v  =  15 – 5

v  =  10
