An auto dealership wants to know the average amount of money its customers can spend on a car. 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. 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
For this question I would put the problem into slope-intercept form or y=mx+b. So add 3x to both sides so that the equation becomes y=3x+3 Then this equation is easier to graph. the y-intercept is 3 so there is a point at (0,3). and the slope is 3 so you would go over 1 up 3. Then connect those points and you have finished the graph. Hope this helps.
