Key club hosted a fundraising event where the profit they made depends on the number of people. if 100 people attend they make $2500. if 80 people attend they make $1500.
like can someone me ?

The linear equation that represent this problem is

Step-by-step explanation:

Let

x -----> the number of people

y ----> the profit in dollars

we have

For x=100, y=2,500

and

For x=80, y=1,500

Find the slope m

we have

(80,1,500) and (100,2,500)

The slope is equal to

Find the equation of the line into point slope form

we have

and point (100,2,500)

substitute

----> equation in slope point form

Convert to slope intercept form

$97520

step-by-step explanation:

add 6% to the value she got from selling the house.
