Answer:
it will take around 15 weeks to for Reiko to make a profit
Explanation:
Given:
Amount spent to obtain merchandise = $5,200
Cost of general expenses = $550
Earnings from sales per week = $900
Now,
Let 'x' be the number of weeks taken to make profit
thus,
Total cost involved = $5,200 + ( $550 × x )
Total profit from sales = $900 × x
for making profit
$900 × x ≥ $5,200 + ( $550 × x )
or
350x ≥ 5,200
or
x ≥ 14.85 weeks
thus,
it will take around 15 weeks to for Reiko to make a profit
