Question

a grocery store scale is accurate to within 0.4 pound. the scale indicates that a bag of apples weighs 3.7 pounds. Which of the following describes all possible weights of the bag of apples?

Answer 1

3.3 lb ≤ Weight ≤ 4.1 lb

Explanation:

The options are not given; however, the question can still be solved.

Given

Weight = 3.7 lb

Range = 0.4 lb

The possible weight is calculated by (1) & (2) below

1. Maximum

Maximum = 3.7 lb + 0.4 lb

Maximum = 4.1 lb

2. Minimum

Minimum = 3.7 lb - 0.4 lb

Minimum = 3.3 lb

Hence, the range the weight of the apple can be is

3.3 lb ≤ Weight ≤ 4.1 lb
