Hi, my 7th grade cousin needs help with this problem, but I'm busy with my own homework to explain it to her. Please help her as fast as you can.

Solve the Iniquality.

The Cookie Factory has a fixed cost of $300 per month plus $0.45 for each cookie sold. Each cookie sells for $0.95. How many cookies must be sold during one month for the profit to be at least $100.

Thank you.

Thank you.

Let number of cookies sold = n

Fixed cost = $300

Selling cost = n * $0.45

Total cost = $300 + n * $0.45

Income = n * $0.95

Income - total cost = profit

Profit >= $100

n * $0.95 - ($300 + n * $0.45) >= $100

n * $0.95 - $300 - n * $0.45 >= $100

n * $0.50 - $300 >= $100

n * $0.50 >= $100 + $300

n * $0.50 >= $400
