A. 0.66 h

B. 3.8 h

C. 0.38 h

D. 2.7 h

Answers

To solve this you would use the equation, d=r*t. So you would take 480=180*t. Or you could use t=480/180. The answer would come out to 2.66 hours, which means the answer would round up to 2.7 hours. The answer would be D.

Company A offers a starting salary of $28,000 with a raise of $3,000 each year. Company B offers a starting salary of $36,000 with a raise of $2,000 per year. Company C offers a starting salary of $18,000. After how many years would the salaries for Companies A and B be the same? How much of a raise per year would Company C have to offer to equal the salaries of Companies A and B in the year in which the salaries of Companies A and B in the year in which the salaries of those two companies are the same?

Answers

Starting salary offered by Company A = $28000
Amount of raise per year given by Company A per year = $3000
Starting salary offered by Company B =$36000
Amount of raise per year given by Company B = $2000
Let us assume the number of years after which the salary offered by Company A will be the same as Company B = x
Then
28000 + 3000x = 36000 + 2000x
3000x - 2000x = 36000 - 28000
1000x = 8000
x = 8000/1000
= 8 years
So from the above deduction we can conclude that after 8 years the salary of Company A and Company B will become equal.
More information's are also provided for the second part of the question.
Starting salary offered by Company C = $18000
Let us assume the amount of raise per year given by Company C = z dollars
Number of years in which the salaries of Company C will become equal to the salaries of Company A and B = 8 years
Then
18000 + 8z = 28000 + (3000 * 8)
18000 + 8z = 28000 + 24000
18000 + 8z = 52000
8z = 52000 - 18000
8z = 34000
z = 34000/8
= 4250 dollars
From the above deduction we can conclude that the raise given by Company C should be $4250.
