Question

A taxi driver charges $10.00 to board his car and $4.00 for every mile driven ( x) which is represented by the linear equation below.

py = 4 x + 10

The variable p represents how many people are in the taxi so that they may split the bill evenly. If two people will be riding in the taxi, what would be the first step in solving the linear equation for the cost of one person?

A. multiplying both sides by 2 because the cost is being cut in half
B. dividing only the right side by 2 because the cost is the only thing being cut in half
C. dividing both sides by 2 because the cost is being cut in half
D. subtracting 2 from both sides because the cost is being cut in half

Answer 1

A. multiplying both sides by 2 because the cost is being cut in half

Explanation:

You multiply both the sides by two to cut the cost in half
