a. Find the number of employees during the second year and during the third year
b. How many employees will this company have during the 10th year?
c. After how many years will the company have 285 employees?

Answer 1

a. 105 and 115 employees

b. 185 employees

c. 20 years

Explanation:

The total of employees at any given year is y

x is the number of year

then y = 85 + 10x

a. 2nd year: y = 85 + 10(2) = 85 + 20 = 105

3rd year: y = 85 + 10(3) = 85 + 30 = 115

b. 10th year: y = 85 + 10(10) = 85 + 100 = 185

c: if y = 285

285 = 85 + 10x

10x = 285 - 85

10x = 200

x = 20
