customers and finds that 25 shoppers can spend $10,000 or less, 15 can spend $10,001 to $25,000, and 10 can spend more than $25,000. If 1000 customers visit the dealership this coming weekend, the dealership can estimate that _____ of its customers will have a budget greater than $25,000. Enter your answer as a number, like this: 42
Given:The dealership surveys 50 random customers and finds that 25 shoppers can spend $10,000 or less, 15 can spend $10,001 to $25,000, and 10 can spend more than $25,000.
To Find: If 1000 customers visit the dealership this coming weekend, the number of customers having budget greater than $25000.
Solution:
Total Number of surveyed customers=
The Number of customers that can spend =
The Number of customers that can spend to =
The Number of customers that can spend more than =
Percentage of people that can spend more than = Number of customers that can spend more than Total Surveyed Customers
=%
If customers visits the dealership,
customer that have budget greater than [= total visiting customers percentage of people that can spend more than
Hence the customers that having budget greater than will be
All you need to do is 4,302 divided by 3. You would get 1434 pounds. I did this in my head. You can split it to get 4,200 divided by 3 + 102 divided by 3. You get 1400 + 34 which is 1434.
solve for y in first equation add 2x to both sides y=2x+8 sub 2x+8 for y in second equation 16+4x=2(2x+8) divide both sides by 2 8+2x=2x+8 true there are infinite solutions for x therefor infinite soltions for y
