Question

A postage box should weigh 1.0 pound. If there is a 5% error on the weight, what is the range of acceptable weight? Explain?

Answer 1

.05

Explanation:

It's simple really. It's finding 5% of 1.

First you change the percent to a decimal. 5%= .05

Next you multiply .05 times 1 which is obviously 1. :)

Answer 2

.95-1.05

Explanation:

you are able to go above 0.05 or below 1 by 0.05

since it's 95% of 1
