Alan has an annual base salary of $18,000. In addition to his salary, he earns 9% of his total sales (S). If he wants to earn at

aivan3 [116]

The right answer is Option D: S>$300,000.

Step-by-step explanation:

Given,

Base salary of Alan = $18000

Commission = 9% = $\frac{9}{100} = 0.09$

Amount Alan wants to earn = $45000 or more

Let,

s be the worth he needs to sell.

Therefore,

Base salary + Commission*Total sales>Amount Alan wants to earn

18000+0.09s>45000

$0.09s>45000-18000\\0.09s>27000$

Dividing both sides by 0.09

$\frac{0.09s}{0.09}>\frac{27000}{0.09}\\s>300000$

Alan must sold items that worth at least $300,000.

The right answer is Option D: S>$300,000.
