Question

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

Answer 1

At 20 pounds it will UPS and FedEx will cost the same!

Explanation:

For UPS, we can write the equation y= 7 + .20x since .20 is the coefficient and 7 is the constant. FedEx's equation would be y= 5 + .30x

Next, set the equations equal to each other: 7 + .20x = 5 + .30x

Now solve for x: 7 + .20x = 5 + .30x

-5 -.20

2 = .10x

20 = x

At 20 pounds it will UPS and FedEx will cost the same!
