Could someone check my work and answers please?
A student who waits on tables at a restaurant recorded the cost of meals and the tip left by single diners. The results are in the table below.
Meal Cost $4.75 $6.84 $12.52 $20.42 $8.97
Tip $0.50 $0.90 $1.50 $3.00 $1.00
Use your calculator write the equation of the line of best fit for this data. Round all values to the nearest hundredth.
y = .16x - .30
If the diner orders a meal costing $10.50, how much tip should the waiter expect to receive? Show your work for how you came up with this number.
y = .16(10.50) - .30
y = 1.68 - .30
y = $1.38
The waiter should expect to receive a tip of $1.38 if a meal costs $10.50
