11. albert started a brownie-making business. he
spent $650 to purchase supplies to get started and
he uses about $2.25 worth of supplies per brownie
made. albert charges $5 for each brownie. let b
represent the number of brownies.
what is the minimum number of brownies albert
will need to sell to make a profit?
write an inequality to solve this situation and then
solve the inequality.

The minimum number of brownies to sell would be 237 brownies

Step-by-step explanation:

Consider the provided information.

Albert spent $650 to purchase supplies to get started and  he uses about $2.25 worth of supplies per brownie  made. Albert charges $5 for each brownie.  

In order to get a profit he need to come up with more than $650

he uses about $2.25 worth of supplies per brownie and charges $5 for each.

Therefore, the profit per brownie is

$5 - $2.25 = $2.75

Let b  represent the number of brownies sold.

The required inequality in order to get profit is:

Now, solving, we get:

So, the minimum number of brownies to sell would be 237 brownies

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
