Question

Bill is planning to drive 1,000 miles to visit his family. If he plans to drive 250 miles per day, which of the following represents the remaining distance d, in miles, that Bill will have to drive to reach his family after driving for n days?

d = 1,000 + 250n
d = 1,000n - 250
d = 250n - 1,000
d = 1,000 - 250n

The correct answer is: d = 1,000 - 250n

The distance Bill have to drive = 1000
The distance Bill travelling each day = 250
If Bill travels n days, the distance covered is 250n
The remaining distance Bill has to cover is = 1000 – 250n
d = 1000 – 250n
