Question

Ed buys a box of eggs costing £2.70 two packs of bacon for £2.50 and two tins of backed beans he pays with a £10 note and gets 70p change

Answer 1

£2.05 for a tin of Baked Beans. ( If 2 packs of bacon cost 2.50)

if not it is £0.80 or 80p and I am guessing the question is "How much does a tin of baked beans cost?"

Explanation:

b = number of boxes of eggs

p = number of packs of bacon

t = number of tins of beans

He has a total of £10.

1 box of Eggs cost £2.70

2 packs of bacon cost £2.50, so one pack costs £1.25

• £10 = 2.70b + 1.25p + xt + 0.70
• £10 = 2.70( 1 ) + 1.25( 2 ) + 2x + 0.70
• £10 = 2.70 + 2.50 + 2x + 0.70
• 4.1 = 2x
• 2.05 = x
