My question is: Robert, a sales agent, earns a basic salary of $1250 per month and, 10% commission on his monthly sales. Last month, his total sales were $23600. He allocated 20% of his total earnings to savings and the rest of the money to his monthly expenses. How much were his monthly expenses last month? Your thoughts:
Robert earned a commission of $23600 x 10 / 100 = $2360. So, he earned a total of $1250 + $2360 = $3610. And, he saved $3610 x 20 / 100 = $722. Therefore, his total expenses last month was $3610 - $722 = $2888. The final answer: 2888.
