Question

Soda cans are sold in three different ways at the supermarket.



What is the cheapest price that someone can buy 14 cans for?

Worked Solution

Two six packs and two cans
= (2 × 7.00) + (2 × 1.20)
= 14 + 2.40
= $16.40

One ten pack and 4 single cans
= 11 + (4 × 1.20)
= 11 + 4.80
= {{{prefix0}}}{{{correctAnswer0}}}

∴\therefore Cheapest price = {{{prefix0}}}{{{correctAnswer0}}}
