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

Total salary will be

150 +.15x=600 where x is the sales

.15x=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.

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.

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.

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

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
Option A
