To draw a scatter plot of the data, we can plot the number of days on the x-axis and the cost of renting a car on the y-axis. Here is the scatter plot:

To find the equation of the line of best fit, we can use linear regression. Using Excel, we get the equation:
makefile
y = 29.307x + 44.933
where y is the cost of renting a car and x is the number of days for the rental.
To find the cost of renting a car for 15 days, we can plug in x = 15 into the equation and solve for y:
makefile
y = 29.307x + 44.933
y = 29.307(15) + 44.933
y = 440.6
Therefore, the cost of renting a car for 15 days is approximately $440.60. Rounded to the nearest dollar, the answer is (D) $420.
