Answer:
You will be able to ride 17 miles.
Explanation:
So to get into the cab you need to pay 3 dollars. For every mile it will cost you 1 dollar. And you can only spend 20 dollars.
The first step to do is subtract 3 from 20.
This gives us 17.
Now that our cab cost is deducted we can divided 17 dollars by 1 dollar.
17 / 1 = 17.
You will be able to ride for 17 miles
