Answer:
72$
Step-by-step explanation
How to insert in a calculator 90-20%= 72
How to take 20% from a price
Divide the original price by 5. <em>18</em>
Subtract this new number from the original one. <em>90 - 18 </em>
The number you calculated is the discounted value. <em>90 - 18 = </em><u><em>72</em></u>
It would show the average time spent on the homework.
And the average distance between the mean and the lowest and highest numbers in the data.
