What percent of all customers are not satisfied with the experience of the self- checkout lane ? Enter your answer as a decimal rounded to the nearest hundredth .

Answer 1

20.40% of all customers are not satisfied with the self-checkout lane experience, calculated by deducting the satisfied customer percentage from the total using self-checkout.

Step-by-step explanation:

The student asked what percent of all customers are not satisfied with the experience of using the self-checkout lane at a grocery store if 85% use the self-checkout and 76% of those are satisfied. To calculate this, we first find the percentage of customers who are satisfied with the self-checkout lane by multiplying the percentage of customers who use it (85%) by the percentage of those who are satisfied (76%), which gives us 64.6% of all customers being satisfied with the self-checkout lane. To find the percentage of customers who are not satisfied, we subtract this number from the total percentage of customers who use the self-checkout lane, giving us 85% - 64.6% = 20.4%. However, the question asks us to round this to the nearest hundredth, which makes it 20.40%.

Therefore, 20.40% of all customers are not satisfied with the experience of using the self-checkout lane.
