James has a job with a current salary of $42,000. he wants to earn a college degree that will take him 2 years to complete and it will cost $28,000 per year. he will go to school full time and will not be able to work. upon graduation, james new salary will be $56,000 per year. how many years will it take james to recover his investment?

28000(2 years) = $56,000 

42,000(2 years unable to work) = $84,000 

56,000 + 84,000 = $140,000 

140,000 ÷ 56,000 = 2.5 years 

This is if the two years of not being able to work is included. If not, then it would only take him one year to earn back his investment.

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
