System of equations and their graph

We have that the equation given by the Option A is:

y = 2x + 10

and the Option B equation is:

y = 3x

If we graph them, we will obtain the following figure:

C

The cost is the same when the two line intercept each other. Their interception at the tenth ride

When this happens the cost is $30

Answer: the total cost of both options is the same at the tenth ride

D

We have that the cheapest plan is always given by the line below.

Before the tenth ride:

the cheapest plan is the Plan B

After the tenth ride:

the cheapest plan is the Plan A

Since Plan A will be the cheaper in the future after Ride number 10, we can say that the cheapest plan is Plan B
