Question from bertha, a student: A real estate broker's base annual salary is $\$18,000.$ She earns 3% commission on total sales. How much must she sell in real estate value during the year to earn $\$65,000?$ Set up an equation and solve. Show all work to receive full credit. Round final answer to the nearest dollar. |
Hi Bertha,
I can help get you started.
Since she has a base salary of $\$18,000$ to have an annual income of $\$65,000$ she needs to make $\$65,000 - \$18,000 = \$47,000$ in commissions. Her commission is 3% of her sales and 3% is $\frac{3}{100}$ so $\frac{3}{100} \mbox{times her sales }$ must be at least $\$47,000.$
I hope this helps,
Penny
