Question

Ed buys a box of eggs costing £2.80, two packs of bacon for £2.40 each and two tins of baked beans. He pays with a £10 note and gets 80p change. How much does a tin of beans cost in pounds, £?

Answer 1

£0.80

Explanation:

egg = 2.80

Bacon = 2 * 2.40 = 4.80

Baked beans = 2 tins

Amount issued = 10

Change obtained = 80p = 0.8

Let cost per baked beans = x

lol

2.80 + 4.80 + 2x = 10 - 0.8

7.60 + 2x = 9.20

2x = 9.20 - 7.60

2x = 1.6

x = 1.60 / 2

x = 0.80

YES WE GOT IT, a tin of baked beans cost £0.80

Answer 2

£0.8

Explanation:

egg = 2.80

Bacon = 2 * 2.40 = 4.80

Baked beans = 2 tins

Amount issued = 10

Change obtained = 80p = 0.8

Let cost per baked beans = x

Hence,

2.80 + 4.80 + 2x = 10 - 0.8

7.60 + 2x = 9.20

2x = 9.20 - 7.60

2x = 1.6

x = 1.6 / 2

x = 0.8

Hence, a tin of baked beans cost £0.8
