Answer:
Explanation:
a. In a regression equation expressed as y= a + bx, how is the letter b best described?
Here, b is the slope and best described as the estimate of the cost when there's a visit of an additional customer.
b. How is the letter y in the regression equation best described?
The letter y is the observed store cost for that particular month.
c. How is the letter x in the regression equation best described?
The letter x is the observed customer visit for that particular month.
d. Based on the data derived from the regression analysis, what are the estimated costs for 370 customer-visits in a month?
The estimated cost for 370 customer visit will be:
Y = a + bx
where, 
a =$1496 
b = $2.08 
x = 370 customer visit
Y = $1496 + ($2.08 × 370 customer visit) 
= $1496 + $769.6
= $2265.6
e. What is the percent of the total variance that can be explained by the regression equation?
The percent of total variance which the regression equation explain will be: 
R2 = 0.86814 or 86.814%

Answer: $900
Explanation:
The Total Capital of the company before Zell was admitted was;
= Capital balances + Goodwill
= 600 + 800 + 700
= $2,100
If they admitted Zell in with a 30% interest, this means that the $2,100 is equivalent to 70% of the company's capital. 
If that is the case then Total capital is;
= 2,100/ 70%
= $3,000
Zell's contribution is;
= 30% * 3,000
= $900
