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

Find the GCF of each pair of monomials. <br> 1). 20, 45x
Helga [31]
 20 and 45x

We look for a number that can go into both numbers.

5 into 20 is 4 and 5 into 45x is 9x.

5:      20       45x

         4           9x

So no other number can go into 4 and 9x again.

So the GCF of 20 and 45x is 5.     

Hope this explains it.
