Mrs. robinson, an insurance agent, earns a salary of $4,800 per year plus a 3% commission on her sales. the average price of a policy she sells is $6,100.

write an inequality to find how many policies mrs. robinson must sell to make an annual income of at least $8,000.

4800+183x< (line under the arrow)=8000
4800+183x=8000
4800+183x> =8000
4800+186> (ine under the arrow)=8000

She must sell at least 18 policies to make an annual income of at least $8,000

Step-by-step explanation:

Let be the number of policies Mrs. Robinson must sell

We know that Mrs. Robins makes 3% on commission for each policy sold. We also know that the average price of a policy is $6,100, so she makes 3% of $6,100 per policy sold. To find the 3% of $6,100 we just need to multiply 3% and $6,100; then dive the result by 100%:

Now we know that she makes $183 per policy sold. Since is the number of policies sold, is her total commission for selling policies.

We also know that She makes $4,800 per year, so her total annual income is her salary plus her commissions, in other words:

Finally, we know that she wants to make at least $8,000, so her salary plus her commissions must be greater or equal than $8,000:

Let's solve the inequality:

1. Subtract 4800 from both sides

2. Divide both sides by 183

Since she can't sell a fraction of a policy, we must round the result to the next integer:

We can conclude that she must sell 18 policies to make an annual income of at least $8,000.
