Part 2: How many more cars were sold during the second quarter of 1999 than in the second quarter of 1998? 15 cars
Explanation:
Part 1: How many cars were sold at Frank's Auto Corner during the second quarter of 1999?
How to: Add the number of cars sold during April, May, and June of 1999. This would be: 89 + 98 + 115 = 302 cars
Part 2: How many more cars were sold during the second quarter of 1999 than in the second quarter of 1998?
How to: Subtract the number of cars sold in the second quarter of 1998 from the number sold in second quarter 1999. We are given that 287 cars were sold in the second quarter of 1998 so: 287 - 302 = 15 cars
