First, let's create an equation for this problem. Remeber, 6% = 0.06
(0.06 × $2,540) + $300
Now, all you would need to do is solve it. You would start in the parenthesis, using the order of operations (PEMDAS).
(0.06 × $2,540) + $300
$152.4 + $300 = $452.4
The salesperson earned $452.5 in a week.
Have a great day!
