Sue and Cath have $20 left for a cab fare home. The cab fare is $3 per mile plus a $2 fixed charge. What is the maximum number of miles they will be able to travel in the cab? Step by Step !!!

6 miles

Step-by-step explanation:

first thing you need to do is find a number under 18 that can be multiplied by 3

3

6

9

12

15

18

and 18 is the 6th number and is 18, you can add the 2 extra fixed charge to that

they can travel 6 miles

but if you're talking about a fixed charge per mile then dont use this! ^^
