A sales representative receives a salary of $150 per week and earns a commission of 15% on all sales she makes. How many dollars’ worth of sales does she need to make in order to bring her total weekly income to $1050? Choose the correct choice from the following answers: A) $3,000 B) $3,150 C) $4,000 D) $4,150 E) $6,000
We're told that a sales representative receives a salary of $150 per week and earns a commission of 15% on all sales she makes. We're asked how many dollars’ worth of sales will bring her total weekly income to $1050.   Since the salesperson receives a $150 salary, the remaining $900 has to be accounted for by the 15% commission. Since those numbers are rather specific, we're likely dealing with a 'round number' for total sales.   Let's TEST Answer C: $4,000   Since 15% of $1,000 = $150   15% of $4,000 = 4($150) = $600   This is TOO HIGH (it's supposed to be $900), so we need a LOWER total sales figure.   Let's TEST Answer E: $6,000   Since 15% of $1,000 = $150   15% of $6,000 = 6($150) = $900   This is an exact MATCH for what we were told, so this MUST be the answer.   Final Answer:   $6,000
