Total salary = $150+ 15% (x) where x = all the sales she makes.

How much x should be for total to be 600

$150+15%(x) = $600
15%(x) = $450
x = $3000

Hi All,

This question can be solved by TESTing THE ANSWERS.

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 $600.

Since the salesperson receives a $150 salary, the remaining $450 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 $450), so we need a LOWER total sales figure.

Let's TEST Answer A: $3,000

Since 15% of $1,000 = $150
15% of $3,000 = 3($150) = $450
This is an exact MATCH for what we were told, so this MUST be the answer.

Final Answer:

GMAT assassins aren't born, they're made,

A. $3,000
B. $3,150
C. $4,000
D. $4,150
E. $5,000


Initial weekly salary = $150
Required weekly salary = $600

Hence she needs $450 more from commissions

She makes 15% from one sales.
Let the sales required = $100x

Commission earned = 15x
15x = 450
Or x = 30

Therefore sales required = 100*30 = $3000
