(x,y) is a solution to an eqn when y = mx + c
A. 2(2)-1 = 3 <>-1
B. 2+3 = 5<>-1
C. 2-3 = -1 = y
so C has (2,-1) as a solution
Answer:
Maximum customer= 53
Minimum customer= 47.
Step-by-step explanation:
Given: On average, 45 people buy lemonade.
Customer can vary by as much as 8 people.
Now, finding maximum and minimum number of customer, Meghan should expect.
We know, the average number of customer in Meghan´s stand is 45.
As given, customer can vary by as much as 8, which means it can increase by 8 customer or decrease by 8 customer.
∴ Maximum customer=
Minimum customer=
Hence, The maximum number of customer is 53 and minimum number of customer is 37.
Set up a system of equations
Let x=first salesperson's paycheck
y=second salesperson's paycheck
x= y-.15y
x+y= 1425
Solve by substituting x
(y-.15y)+y= 1425
1.85y= 1425
y= 770.27
Substitute 770.27 for y in order to solve for x
x= (770.27)-.15(770.27)
x= 770.27-115.54
x=654.73
So the first salesperson(x) has a paycheck of $654.73 and the second salesperson(y) has a paycheck of $770.27.
Hope this helps!
