The cost of riding in a taxi cab is $4 plus $2 per mile.
The total cost is represented by the variable c.
This equation can be used to find the total cost (c) of riding 3 miles in a taxi cab.
c=2x3+4
What is the total cost of riding 3 miles in a taxi cab?

c=10

Step-by-step explanation:

First thing you need to do is set up the equation that will help you solve:

4+2m=c ; where m is miles

Then you plug in the 3 for m;

4+2(3)=c

In total you will get;

10 = c

452,489 to the nearest thousand is 452,000

1) is right
