Jerome makes 1/3 of the whole profit. So to find the overall profit of the company, multiply his profit by 3.
If he makes $150,000 this is how you would solve:
150,000•3= $450,000
450,000 dollars is your answer.
The dot is just a multiplication sign.

Hope you could get an idea from here.

Answer:
The degrees of freedom for this sample are 27.
The sample size to get a margin of error equal or less than 0.3656 is n=4450.
Step-by-step explanation:
The degrees of freedom for calculating the value of t are:

With 27 degrees of freedom and 95% confidence level, from a table we can get that the t-value is t=2.052.
The sample size to get a margin of error equal or less than 0.3656 can be calculated as:
