Answer:

a.  x = 8 years

b.  52,000

Step-by-step explanation:

company A = 28,000 + 3,000 (x)

company B = 36,000 + 2,000 (x)

where x = no. of years.

  • company A = company B

28,000 + 3,000 (x) = 36,000 + 2000 (x)

3,000 (x) - 2,000 (x) = 36,000 - 28,000

1,000 (x) = 8,000

x = 8,000

     1,000

x = 8 years

  • plugin value of x = 8 into company A and B

company A = 28,000 + 3,000 (8)

company A = 52,000

company B = 36,000 + 2,000 (8)

company B = 52,000
