Answer:
The correct answer is 32.88.
Step-by-step explanation:
Cost price for a 26 ounce can of coffee = 6.75.
A case of coffee contains 12 cans.
Total cost price of a case is 12 × 6.75 = 81.
Selling price of each can of coffee = 9.49.
Total selling price of a case is 12 × 9.49 = 113.88.
Total profit for selling a case of cnas of coffee is given by 113.88 - 81 = 32.88
Thus the profit for selling each can is 32.88.
Answer:
Step-by-step explanation:
x/4 - y/3 = 1..multiply everything by the LCD....which is 12
3x - 4y = 12 <== standard form
=====================================
if it makes it easier for u, x/4 is the same as (1/4)x and y/3 is the same as (1/3)y
so ur problem can be written as : (1/4)x - (1/3)y = 1....multiply by 12
12(1/4)x - 12(1/3)y = 12(1)
(12/4)x - (12/3)y = 12.....reduce
3x - 4y = 12
Answer:
The margin of error for a 90% confidence interval is 16.4
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 25
Standard deviation = 50
Margin of error =
Putting the values, we get,
Thus, the margin of error for a 90% confidence interval is 16.4
