A convenience store makes a profit of $2 per bottle of a healthy drink. If the store owner wants to earn a profit of at least $400, how many bottles of this drink do they need to sell
They need to sell at least 200 bottles of the healthy drink to earn a profit of at least $400.
Calculation:
Profit per bottle = $2
Total profit desired = $400
Number of bottles needed to sell = Total profit desired / Profit per bottle
Number of bottles needed to sell = $400 / $2
Number of bottles needed to sell = 200 bottles
Therefore, the store owner needs to sell at least 200 bottles of the healthy drink to earn a profit of at least $400.
