Eric is preparing for a regional swim meet that is a month away. He swims the same distance and clocks his best time on several different days. He plots the best time (in minutes) he swam each day as his y-variable and the day he
swam it as his x-variable. When he plots his times and finds a line of best fit, he gets the equation
y = -0.03x + 3.45.
If Eric continues to practice, what will be his approximate best time on the 15th day?
Enter the answer as the correct value without units.
