UPS charges $7 for the first pound, and $0.20 for each additional pound. FedEx charges $5 for the first pound and $0.30 for each additional pound. How many pounds will it take for UPS and FedEx to cost the same? Write an equation.

• 7p +0.20 = 5p + 0.30
• 0.20p + 7 = 0.30p + 5
• 7 - 0.20p = 5 - 0.30p
• 0.20p - 7 = 0.30p - 5
