Question

Kane’s bakery makes 4 flavour of pie. The weight of each flavour pie is follow:

Apple pie - 700g
Banoffee pie - 725g
Custard pie - 600g
Rhubarb pie - 675g

Robert makes an order for 4 apple pies, 8 banoffee pies, 3 custard pies & 5 rhubarb pies to sell at a fundraiser.
Kane packs the order into boxes that can each hold 4kg. What is the fewest number of boxes he can pack the order into?

Answer 1

The total mass of the order is
.. 4*(.700 kg) +8*(.725 kg) +3*(.600 kg) +5*(.675 kg) = 13.775 kg
.. 13.755/4 ≈ 3.44, so a minimum of 4 boxes will be required.

The pies can be packed 5 to a box in any combination.
The order will require 4 boxes
