You give 1/2 up a $46,000 salary to go back to school for 5 years. The total cost for going to school is $22,000. How much money
Ket [755]

The individual needs to earn $74,750 salary per year in order to recover the investment in 4 years.

What salary amount makes the individual as they were without a salary cut?

By the time the individual resumes back for work after 5 years, they need to earn their previous salary of $46,000 and recover the lost salaries, which is half of $46,000 lost in the last 5 years.

Total salaries lost=1/2*$46,000*5years

Total salaries lost=$115,000

Because the salaries lost needs to be recovered over 4 years, the extra earnings over and above the $46,000 in 4 years is the total salaries lost divided by 4 years

extra salary per year=$115,000/4

extra salary per year=$28,750

Total salary now=prior salary+ extra salary per year

Total salary now=$46,000+$28,750

Total salary now=$74,750

you are ordering linoleum for an 18' by 15' kitchen but when you get to the store the mesurments are in square yards, how much s
Damm [24]
18' by 15' simply means 18 feet by 15 feet.

simply convert feet into yards.

1 yard = 3 feet

18 feet * 1yd/3ft = 6 yards
15 feet * 1yd/3ft = 5 yards

Get the area in square yards:

6 yards x 5 yards = 30 square yards.

You should order 30 square yards of linoleum to cover your 18' by 15' kitchen.
