Question

1. a student who waits on tables at a restaurant recorded the cost of meals and the tip left by diners. if the next diner orders a meal costing $10.50, how muh tip should the waiter expect to receive? type a response

Explanation:

Step1: Calculate the tip percentage for each meal

For the first meal: $\frac{0.50}{4.75}\approx 0.1053$ (or $10.53\%$)
For the second meal: $\frac{0.90}{6.84}\approx 0.1316$ (or $13.16\%$)
For the third meal: $\frac{1.50}{12.52}\approx 0.1198$ (or $11.98\%$)
For the fourth meal: $\frac{3.00}{20.42}\approx 0.1469$ (or $14.69\%$)
For the fifth meal: $\frac{1.00}{8.97}\approx 0.1115$ (or $11.15\%$)

Step2: Find the average tip percentage

Sum of tip percentages: $0.1053 + 0.1316+0.1198 + 0.1469+0.1115=0.6151$
Average tip percentage: $\frac{0.6151}{5}=0.12302$ (or $12.302\%$)

Step3: Calculate the tip for a $\$10.50$ meal

Tip amount = $10.50\times0.12302\approx 1.29$

Answer:

The waiter should expect to receive approximately $\$1.29$
