Answer:
£69.75
Step-by-step explanation:
Given
No. of pairs of shoes bought by Liz = 2
she gave attendant three crisp £50 notes
total money given by Liz = £50*3 = £150
Money she was returned = £10.50.
thus, the money kept with attendant is price of two pair of shoes
price of 2 pair of shoes = total money given by Liz - Money she was returned
price of 2 pair of shoes = £150 - £10.50 = £139.50
To find price of 1 pair of shoes we divide both LHS and RHS by 2
price of 2/2 pair of shoes = £139.50/2 = £69.75
price of 1 pair of shoes = £69.75 Answer
