Question

Which is better value for money: 2 pizzas for £12 or 4 pizzas for £28?

Answer 1

Answer:

2 pizzas for £12.

Step-by-step explanation:

$\frac{2}{12}: \frac{1}{y}$

y · 2 = 12 · 1

2y = 12

2y ÷ 2 = 12 ÷ 2

y = 6

£6 for 1 at the price of 2 for £12.

$\frac{4}{28}: \frac{1}{y}$

y · 4 = 28 · 1

4y = 28

4y ÷ 4 = 28 ÷ 4

y = 7

£7 for 1 at the price of 4 for £28.

Answer 2

For the first one, each pizza is $6

For the second one, each pizza is $7

The first one is the answer
