Final answer:
To find the total price, we calculate the cost of each packet based on the given offers. The total price for 4 packets of fig rolls and 9 packets of crisps is £8.79.
Step-by-step explanation:
To find the total price for 4 packets of fig rolls and 9 packets of crisps, we need to calculate the cost of each packet based on the given offers.
For the fig rolls, the normal price of a 125g packet is £1.34. With the offer of buy one get 2nd half price, the cost of the second packet is £1.34 / 2 = £0.67. So, for 4 packets, the total cost of fig rolls is (1 * £1.34) + (1 * £0.67) + (1 * £1.34) + (1 * £0.67) = £4.02.
For the crisps, the normal price of a 175g packet is £1.59. With the offer of three for the price of two, the cost of each packet is £1.59 / 3 = £0.53. So, for 9 packets, the total cost of crisps is (3 * £0.53) + (3 * £0.53) + (3 * £0.53) = £4.77.
Therefore, the total price for 4 packets of fig rolls and 9 packets of crisps is £4.02 + £4.77 = £8.79.
