Final answer:
To determine the cost with offers of buy one get one free for T-shirts and 3 for 2 for jumpers, we calculate the cost of one T-shirt and four jumpers, leading to a total of £46.60 for 5 jumpers and 2 T-shirts.
Step-by-step explanation:
To calculate the total cost for 5 jumpers and 2 T-shirts with the special offers applied, we follow these steps:
The buy one get one free offer on T-shirts means the customer pays for one T-shirt and gets the second for free. Since the normal price of a T-shirt is £7.40, the cost for 2 T-shirts will be £7.40.
For the jumpers, the 3 for 2 offer means the customer pays for 2 jumpers and gets the third free. To get 5 jumpers, the customer has to pay for 4 jumpers (since the fifth one would be part of a new set of 3 for the price of 2, but there is only one jumper in that last set). So, the cost for 4 jumpers is 4 × £9.80 = £39.20.
The combined cost for the 5 jumpers and 2 T-shirts is £7.40 (for the T-shirts) + £39.20 (for the jumpers) = £46.60.
The total cost for purchasing 5 jumpers and 2 T-shirts using the offers as appropriate is £46.60.
