Answer 2

8 miles

Step-by-step explanation:

Step-by-step explanation:

We have a taxi ride where the total fare is $3 plus $2 for every mile travelled plus a $1 tip and the whole thing is $20.

Let's first write a formula that expresses the cost of the ride:

Total cost

=

Flat fee

+

Mileage

+

Tip

Now let's drop in what we know:

20=3+2(miles)+1

- we know the total cost of 20, the fee of 3, the tip of 1 and the cost per mile of 2. The only thing we don't know is the number of miles. So let's solve for that.

First we subtract 3 and 1 from both sides and get:

16=2(miles)

Then we divide both sides by 2:

8=miles
