Final answer:
To find the total amount paid in a restaurant for main courses and desserts ordered by a group of 24 and 17 people respectively, multiply the cost of each item by the number of people who ordered and sum the totals together, resulting in a grand total of £421.75.
Step-by-step explanation:
To calculate the total amount paid in a restaurant by a group of people for main courses and desserts, we need to use multiplication and addition. Given main courses cost £13.50 and desserts cost £5.75, and knowing that 24 people ordered a main course and 17 people ordered a dessert, we can find the total cost of each item by multiplying the cost by the number of people ordering that item. Then we add both totals together for the overall total.
- Multiply the cost of a main course (£13.50) by the number of people who ordered it (24).
- Multiply the cost of a dessert (£5.75) by the number of people who ordered it (17).
- Add both results to find the total amount paid.
Main courses: £13.50 x 24 = £324.00
Desserts: £5.75 x 17 = £97.75
To find the total amount paid, we now add the cost of main courses and desserts together.
Total amount paid: £324.00 + £97.75 = £421.75
So, the total amount paid by all the people at the restaurant was £421.75.
