Answer 1

B

Explanation:

Margin of Error is simply a range, an amount that is allowed for in case of miscalculation or change of circumstances. The margin of error is 5%.

1. Find the 5% of 3.20 = .16

2. Subtract and add .16 to 3.20 to get rid of that margin of error

3.20 + .16 = 3.36 and 3.20 - .16 = 3.04

3. 3.04 and 3.36

Answer 2

b 3.04 to 3.36

Explanation:

First we need to find 5% of 3.20

.05*3.20 = .16

To find the lower value, subtract 16 cents from 3.20

3.20-.16 = 3.04

To find the upper value, add 16 cent to 3.20

3.20 + .16 = 3.36

The range is 3.04 to 3.36
