Write an solve the equation for the scenario:

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, p, will it take for UPS and FedEx to cost the same?

• Equation: 7 + 0.20p = 5 + 0.30p / Solution: p = 20

• Equation: 7 + 0.20p = 5 + 0.30p / Solution: p = 0.05

• Equation: 7p + 0.20 = 5p + 0.30 / Solution: p = 0.05

• Equation: 7 + 0.20p = 5 + 0.30p / Solution: p = 120
