Question

tim buys a torch and a battery. the torch costs 11 times as much as the battery. tim pays with a £10 note and gets £4.84 change how much does the battery cost?

Answer 1

43 p

Explanation:

total cost = 10 - 4.84 = 10.00 - 4.84 = £5.16

b + t = 5.16

t = 11b

b + 11b = 5.16

12b = 5.16

12 / 12 b = 5.16/12

b = £0.43
