Answer 1

• See below

Explanation:

The first part solved only. The second part is incomplete.

Using the information we build the equation for salary calculation:

• S(x) = (x - 2014)*6000 + 250000, where S is the annual salary at year x, provided x > 2014

Use the equation and work out salary:

• S(2015) = 1*6000 + 250000 = 256000
• S(2016) = 2*6000 + 250000 = 262000
• S(2018) = 4*6000 + 250000 = 274000
• S(2020) = 6*6000 + 250000 = 286000
• S(2021) = 7*6000 + 250000 = 292000
