Question

An employee earns $48,000 in the first year with a company. Every year, the annual salary increases by $4,500. How much is earned during eight years with the company? $388,500 $420,000 $510,000 $636,000

Answer 1

Since every year, the annual salary increases by $4,500, then in the second year the employee earns:

$48000+4500=52500.$

In the third year the employee earns:

$52500+4500=57000.$

In the fourth year, the employee earns:

$57000+4500=61500.$

In the fifth year, the employee earns:

$61500+4500=66000.$

In the sixth year, the employee earns:

$66000+4500=70500.$

$61500+4500=66000.$

In the seventh year, the employee earns:

$70500+4500=75000.$

Finally, in the eighth year, the employee earns:

$75000+4500=79500.$

Therefore, during eight years with the company the employee earned:

$\begin{gathered} 48000+52500+57000+61500+66000+70500+75000+79500 \\ =510000. \end{gathered}$

Answer: Third option $510,000.
