Panchito has a business selling computers. He buys computers from the manufacturer for $450 each and sells them for $800. Each month, he must also pay fixed costs of $3000 for rent and utilities at his store. If he sells n computers in a month, which of the following equations can be used to calculate his profit?

• P=800n - n(450+3000)

• P=(800 - 450)n -3000

• P=(800 - 450)n +3000

• P = 3000x n(800-450)
