Question

So If Mr. Cohen drives 84 2/10 miles on Tuesday,84 6/10 miles on Wednesday,85 miles on Thursday how many miles would He drive on Sunday

Answer 1

Because the miles Mr. Cohen drives increase by
`(2)/(5)` on each day, so Mr. Cohen will drive
`85 + (2)/(5)` × 3 = 86
`(1)/(5)` on Sunday

Answer 2

I think that he would drive 86 7/10 miles because it goes up by 4/10 miles each day
