Answer 1

The minimum number of brownies to sell would be 237 brownies

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:

`2.75b > 650`

Now, solving, we get:

`b > (650)/(2.75)`

`b >236.36`

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