Answer 1

£57.60

Explanation:

The price of a T-shirt = £5.20

The price of a jumper = £10.50

To get 6 T-shirts, since there is an offer of buy one get one free; then the number of T-shirt to be paid for would be:

`(n)/(2)` =
`(6)/(2)` = 3

The price of 3 T-shirts = £5.20 x 3

= £15.60

To get 6 jumpers, since there is an offer of buy 3 get 2 free; then the number of jumper to be paid for is 4.

The price of 4 jumpers = £10.50 x 4

= £42.00

Total cost of 6 jumpers and 6 T-shirts = £15.60 + £42.00

= £57.60
