Final answer:
To find the tip amounts in dollars, calculate the total bill amount for each scenario by adding the cost of the dishes and the sales tax. Then, multiply the total bill amount by the given tip percentages to find the tip amounts. Order the tip amounts from least to greatest.
Step-by-step explanation:
To determine the tip amount in dollars, you need to find the total bill amount first. The total bill amount includes the cost of the dishes and the sales tax. The sales tax is 8% of the cost of each dish. Let's calculate the total bill amount for each scenario:
- For 5 dishes, the total bill amount is $8 x 5 = $40. The sales tax is 8% of $40, which is $40 x 0.08 = $3.20. The tip amount is 17.5% of $40 + $3.20 = $7.20.
- For 6 dishes, the total bill amount is $8 x 6 = $48. The sales tax is 8% of $48, which is $48 x 0.08 = $3.84. The tip amount is 14% of $48 + $3.84 = $7.92.
- For 7 dishes, the total bill amount is $8 x 7 = $56. The sales tax is 8% of $56, which is $56 x 0.08 = $4.48. The tip amount is 11% of $56 + $4.48 = $8.16.
- For 4 dishes, the total bill amount is $8 x 4 = $32. The sales tax is 8% of $32, which is $32 x 0.08 = $2.56. The tip amount is 20% of $32 + $2.56 = $7.12.
