You can put this solution on YOUR website! on a school trip, y minibuses are needed. each minibus will hold 14 pupils. after filling up each minibus the last minibus has 3 spare seats.
a)write an expression for the number of pupils going on the trip.
# of pupils = 14*(number of minibuses)-3
p = 14m - 3
--------------------------
b)the teacher counts 81 pupils getting on the minibuses. Use this information to form an equation.
81 = 14m - 3
------------------------
c) Solve this equation to find out how many minibuses were used.
14m = 81+3
14m = 84
m = 6 mininbuses
