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
