Answer:the percent of increase of sales at the car lot is 6%
Step-by-step explanation:
Number of cars sold last year is 600.
Number of pickups sold last year is 200.
This year, the number of cars increased by 12%. This means that the amount by which the number of cars that was sold this year increased would be
12/100 × 600 = 0.12 × 600 = 72
Therefore, the number of cars sold this year would be
600 + 72 = 672
This year, the number of the pickups sold decreased 12%. This means that the amount by which the number of pickups that was sold this year decreased would be
12/100 × 200 = 0.12 × 200 = 24
Therefore, the number of pickups sold this year would be
200 - 24 = 176
The total number of vehicles sold last year is 200 + 600 = 800
The total number of vehicles sold this year is 672 + 176 = 848
The amount by which the sales increased would be 848 - 800 = 48
Therefore, the percent of increase of sales at the car lot would be
48/800 × 100 = 6%
