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.

What equation can be used to find how many pounds it will it take for UPS and FedEx to cost the same?

Answer 1

The costs will be the same at 21 pounds.

Explanation:

Let p be the number of additional pounds. (Total weight would be p+1).

UPS cost = 7 + 0.20p

FedEx cost = 5 + 0.30p

We need these to be equal.

7 + 0.20p = 5 + 0.30p

0.10p = 2

p = 20
