Alright, lets get started.
Suppose previously I was selling product per week = x
As per question, I have decreased my average number of product by 15 %
Means I have decreased number of product by : x * 15 % = x * 0.15 = 0.15 x
So, the new average product = x - 0.15 x = 0.85 x
As per given question, the new average product = 21.25
0.85 x = 21.25
Dividing by 0.85 in both sides
0.85 x / 0.85 = 21.25 / 0.85
x = 25
Hence it means, 25 products were selling previuosly. : Answer
Hope it will work :)
Answer:
$ 3051
Step-by-step explanation:
Original cost = $ 1000
Marked up Price = Original cost + 170% of 1000
= 1000 + 1.7 * 1000
= 1000 + 1700
= $ 2700
Sales tax = 13% of 2700
= 0.13 * 2700
= 351
Total cost paid by Bernie = 2700 + 351 = $ 3051
Answer:
0.1587
Step-by-step explanation:
Let X be the commuting time for the student. We know that . Then, the normal probability density function for the random variable X is given by
. We are seeking the probability P(X>35) because the student leaves home at 8:25 A.M., we want to know the probability that the student will arrive at the college campus later than 9 A.M. and between 8:25 A.M. and 9 A.M. there are 35 minutes of difference. So,
= 0.1587
To find this probability you can use either a table from a book or a programming language. We have used the R statistical programming language an the instruction pnorm(35, mean = 30, sd = 5, lower.tail = F)
C cause 9 and 243 are the suplies and 4 and x are the number of houses that can be made
