A sales representative receives a salary of $200 per week and earns a commission of 20% 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 $600?
Select the correct option:
A) $3,000	B) $2,000	C) $4,000	D) $4,150	E) $5,000
We're told that a sales representative receives a salary of $200 per week and earns a commission of 20% on all sales she makes. We're asked how many dollars’ worth of sales will bring her total weekly income to $600.   Since the salesperson receives a $200 salary, the remaining $400 has to be accounted for by the 20% 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 20% of $1,000 = $100   20% of $4,000 = 4($200) = $800   This is TOO HIGH (it's supposed to be $400), so we need a LOWER total sales figure.   Let's TEST Answer B: $2,000   Since 20% of $1,000 = $200   20% of $2,000 = 2($200) = $400   This is an exact MATCH for what we were told, so this MUST be the answer.   Final Answer:   $2,000
