Skylar owns a trucking company. for every truck that goes out, skylar must pay the driver $11 per hour of driving and also has an expense of $3 per mile driven for gas and maintenance. on one particular day, the driver drove an average of 30 miles per hour and skylar's total expenses for the driver, gas and truck maintenance were $909. write a system of equations that could be used to determine the number of hours the driver worked and the number of miles the truck drove. define the variables that you use to write the system.

The set of needed equations is

h = 30 m

11 m +  3  h = 909  where

the driver drove for m hours.

h : distance covered in m hours

Step-by-step explanation:

Here, according to the question:

The per hour rate of driver  = $11

The gas maintenance expense = $3 per mile.

The total distance covered by drives is 30 miles per hour.

The total  expenses paid to driver  = $909

Now, let us assume the driver drove for m hours.

The average speed of driver was 30 miles / hour

⇒ Driver covers 30 miles in 1 hour

SO, distance covered in m hours  = h = m x 30 = 30 m

or, h = 30 m

So,according to the question, the total amount paid :

Charges of m hours driving + maintenance charges for h miles

= 11 m + 3( h)

or, 11 m +  3  h = $909

Hence the set of needed equations is

h = 30 m

11 m +  3  h = 909

what is a pre-existing condition claus?

means if you're already damaged some way when you take out a medical insurance you will not get full compensation for that injury that you already have.

the answer is b i just did that
