Use kepler's law, which states that the square of the time, t, required for a planet to orbit the sun varies directly with the cube of the mean distance, a, that the planet is from the sun. using the earth's time of 1 year and mean distance of 93 million miles, find the equation relating t in years and a in millions of miles

Annual wage is $51,300 and you get the other benefits which you add to the original amount 

$51,300 + $2830 + $4600 = 58,730

now they drive the car which costs $600 per month and their are 12 months in a year so

600 x 12 = 7200 

thats deducted from the original salary

58,730 - 7200 = $51530

but the reimburse him $ 0.54 per mile and he drove 36000 miles so 

0.54 x 36000 = 19440

so you add that to the amount and that should lead you to the answer :) good luck!
