Bri opened a lemonade stand on her street it cost her 11 dollars a day for supplies and she sells lemonade for $2 a cup if she wants to make at least $75 if profits how many cups of lemonade will bri need to sell

Bri's daily profit can be calculated by subtracting the cost of supplies from the revenue generated by selling lemonade:

Profit = Revenue - Cost
Profit = ($2 * cups sold) - $11

To make a profit of at least $75, Bri must sell enough cups of lemonade to cover her daily cost and make an additional $75:
$75 = ($2 * cups sold) - $11
$75 = $2 * cups sold - $11
$75 + $11 = $2 * cups sold
$86 = $2 * cups sold
cups sold = $86 / $2
cups sold = 43

Therefore, Bri will need to sell at least 43 cups of lemonade in order to make a profit of at least $75.
