Answer:
The possible values of the number of dollars in the original pile of money is ≥ $200 but < $350
Step-by-step explanation:
Here we have, pile of money ≥ $200
Amount in put the left pocket = $50
Fraction given away = 2/3 of rest of pile ≥ 2/3×150 ≥ $100
Amount put in right pocket = ≥ $150 - $100 ≥ $50
Total amount remaining with Jeri = $50 +≥ $50 ≥ $100
Also original pile - $200 < $100
Therefore where maximum amount given away to have more money = $200 we have
2/3× (original pile - 50) = $200
Maximum amount for original pile = $350
Therefore the possible values of the number of dollars in the original pile of money is ≥ $200 but < $350.
The prediction of the editor is not correct
Step-by-step explanation:
Step 1 :
Given,
Percentage of email that comes back undelivered = 3%
Number of email the editor sends out = 12181
Number of email predicted by the editor which is undelivered = 433
Step 2 :
To compute the actual number of emails undelivered we need to compute 3% of the emails that is actually sent.
= 3% of 12181 = 0.03 * 12181 = 365.43 which is 366 rounded to the closest integer.
Step 3:
Hence we can conclude that the prediction of the editor is not correct as only 366 undelivered notices are received back as against his prediction of 433 notices.
