Answer:
Your total earning for the week is $260
Explanation:
You earn a salary of $200 weekly, which is constant. Then there is 3% commission on sales you make weekly too.
So it you make $2000, your commission is
3/100 × 2000 = $60
So your total earning for the week is constant income (salary) + commission, which is
$200 +$60 = $260
