Final answer:
The Stevens family's total cost for cinema tickets requires ticket prices, which are not provided. With hypothetical prices for adults ($10), children ($8), and a senior discount (20%), the example calculation totals $44 for 3 adults and 2 children. Similarly, Mr. and Mrs. Green's dinner cost is found by calculating an 18% tip on their $72 meal to get a total of $84.96.
Step-by-step explanation:
The question you are asking is related to Mathematics, specifically to the calculation of total costs given individual costs and percentages. To calculate the total cost of the Stevens family going to the cinema, you would need the price of tickets for 3 adults and 2 children, including any discounts that may apply for the senior adult who is 67 years old. Since we do not have the actual ticket prices, I cannot provide a definitive answer. However, I can show you how to calculate the cost with an example:
- Determine the price of an adult ticket and a child ticket.
- Add the cost of 3 adult tickets.
- Add the cost of 2 child tickets.
- Apply any senior discounts to the cost of the senior’s ticket if available.
- Add all the costs together to find the total cost for the Stevens family.
As an illustrative example (using hypothetical prices), let’s say adult tickets are $10 each, children’s tickets are $8 each, and the senior discount is 20% off for individuals over 65:
- The cost for the adults would be 2 * $10 (regular adults) + $10 * 0.80 (senior discount) = $20 + $8 = $28.
- The cost for the children would be 2 * $8 = $16.
- So, the total cost for the Stevens family would be $28 (adults) + $16 (children) = $44.
The following example from Mr. and Mrs. Green’s dinner illustrates a similar calculation:
Cost of the meal: $72
Tip percentage: 18%
Amount of the tip: $72 * 0.18 = $12.96
Total cost of the dinner: $72 + $12.96 = $84.96
