Margin of error is the chances of percentage deviation that may differ from original population data. The margin of error for 95% confidence interval can be 6.25%.

Answer:
His salary is $2666.68
Step-by-step explanation:
First add the percent of the costs. 10% + 15% = 25%
Then subtract 25% from 100% to find the percentage that 2,000 is of the total salary. 100% - 25% = 75%
$2,000 is 75% of the total salary. Divide 2,000 by three to find the amount of money 25% of the salary is. ( 75% is 3/4 of 100) 2,000 divided by 3 = $666.67
25% of the salary is $666.67
Multiple that by 4 and you get the total salary.
666.67•4= $2666.68
