Answer and Explanation
Q5.1 — c: £43.89
The cost of the ingredients is 158 / 1.2 / 3 = £43.89.
Q5.2 — e: £201.60
The party would pay: 50 x 3 x 1.2 (VAT) x 1.12 (service) = £201.60.
Q5.3 — b: £17.22
Without the wine, the total bill for the food is 172 — 48 = £124. The cost of the ingredients per person is therefore: 124 / 1.2 (VAT) / 3 (cost multiplier) / 2 (number of people) = £17.22.
Q5.4 — e: £288
We know that the ingredients cost £32, therefore the price charged to cus-tomers for the food part of the meal will be 32 x 3 x 1.2 = £115.20. Since the drinks account for 60% of the total bill, then the food accounts for 40%. Therefore the total bill is: 115.20 / 0.4 = £288.
