hey you have to understand the Q first correctly that we have to report something to company.... the things are total mileage and fuel comsumed in the last month... so there will be 3 columns for the matric and rows equal to number of drivers

OpenStudy (anonymous):

so between option one no. of trips mileage(x1000mi) fuel used(x1000 gal) driver 1 | 8 7.68 1.01 driver 2 | 7 9.94 1.33 driver 3 | 12 1.79 14.33 driver 4 | 12 2.05 13.92 option 2 no. of trips mileage(x1000mi) fuel used(x1000 gal) driver 1 | 8 7.68 1.01 driver 2 | 7 9.94 1.33 driver 3 | 12 14.94 1.79 driver 4 | 12 13.92 2.05
