Question

Bella buys

4 packets of sandwiches at £2.40 each packet
a bottle of water for £1.20
and 3 packets of crisps.
Bella pays with a £20 note.
She gets £5.75 change.
Each packet of crisps has the same price.
Work out the price of each packet of crisps.

Answer 1

The crisps cost 1.15 pounds

Explanation:

We can write this in the form of an equation:

4×2.40+1.20+3x=20-5.75

9.6+1.20+3x=14.75

10.8+3x=14.75

3x=14.75-10.8

3x=3.45

x=1.15

Hope this helps!
