Answer: option 2 is the cheapest
Step-by-step explanation:
Option 1 :
10% of 4.99 = 0.499
10% off 4.99 =
4.99 - 0.499 = 4.491
10% of 15.99 = 1.599
10% off 15.99 =
15.99 - 1.599 = 14.391
10% of 30.99 = 3.099
10% off 30.99=
30.99 - 3.099 = 27.891
Total = 4.491 + 14.391 + 27.891 = 46.773
Option 2 :
Most expensive item = 30.99
20% of 30.99 = 6.198
20% off 30.99=
30.99 - 6.198 = 24.792
Total = 24.792 + 15.99 + 4.99 = 45.772
Therefore, option 2 is cheaper by 1.001.
Hope this helped :)

-3 times positive 1 is negative 3
Using the Empirical Rule, it is found that the proportion of people in a population with IQ scores between 80 and 140 is of 0.95 = 95%.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
Considering the mean of 110 and the standard deviation of 15, we have that:
These values are both the most extreme within 2 standard deviations of the mean, hence the proportion of people in a population with IQ scores between 80 and 140 is of 0.95 = 95%.
