Items purchased:
x packs of pencils,
twice as many packs of erasers, total number of eraser packs = 2x
three times the number of tape rolls, number of tape rolls = 3x
total expenditure = x m + 2xn + 3xp = x(m + 2n + 3p)
We now have two possibilities:
1- All three goods are the same price:
cost of one pencil pack = cost of one eraser pack = cost of one roll of tape = m
x m + 2xm + 3xm = 6xm
total amount spent
2- The three goods are not the same price:
m = the cost of one pencil pack
n = the cost of one pack of erasers
One roll of tape costs p.
total expenditure = x m + 2xn + 3xp = x(m + 2n + 3p)
