Answer 1

Answer:

Her net rate of pay in dollars per hour after the expense = $26

Step-by-step explanation:

Given:

Driver travels for 2 hours.

Speed = 60 miles per hour

Her  car runs at the rate of 30 miles per gallon of gasoline.

She is paid $0.50 per mile.

Expenses is price of gasoline at the rate of $2.00 per gallon.

To find her net rate of pay in dollars  per hour.

Solution:

In one hour the driver travels = 60 miles

For each mile she is paid = $0.50

So, for 60 miles she will be paid = $60\times \ 0.50 = \ 30$

In a gallon of gasoline the car travels = 30 miles

So, to travel 60 miles, the car would require = $\frac{60}{30}= 2$ gallons of gasoline

1 gallon of gasoline cost = $2.00

Expenses for 2 gallons of gasoline = $2\times \ 2.00=\ 4$

So, in one hour she gets paid =$30 and her expenses for an hour drive = $4.

Thus, her net rate of pay in dollars per hour after the expense = $\ 30-\ 4=\ 26$
