Answer 1

City cabs charge a 2.25 pickup fee and 1.25 per mile traveled.

Diego's fare for a cross-town cab ride is $22.25.

How far did he travel in the cab?

He traveled 16 miles in the cab.

Answer 2

22.25-2.25=20/1.25=16 miles.

Answer 3

If the pickup fee is $2.25 and $1.25 per mile, then the cost function for this is:

C(x) = 1.25x + 2.25

So what's the miles if the fare is $22.25?  Solve for x when C(x) = 22.25:

22.25 = 1.25x + 2.25

20 = 1.25x

20/1.25 = x

x = 16 miles

Answer 4

First subtract the pickup fee.  22.25 - 2.25 = 20.00

Now divide 20.00 by 1.25.  I get 16.  That's 16 miles.
