Percent of earnings that go to school = 80%
Percent of earnings that was spent on the fundraiser cost = 20%
Last year earnings were= $4000
80% of 4000 went to school which is =
![\frac{80}{100}\times4000=3200](https://tex.z-dn.net/?f=%5Cfrac%7B80%7D%7B100%7D%5Ctimes4000%3D3200)
20% of 4000 =
went to costs.
a:
As given, this year, they want $4,000 to go directly to the school.
So let the earnings this year be represented by = x
As, 80% of the earnings go to school, so 80% of x = 4000
![\frac{80}{100}*x=4000](https://tex.z-dn.net/?f=%5Cfrac%7B80%7D%7B100%7D%2Ax%3D4000)
![80x=400000](https://tex.z-dn.net/?f=80x%3D400000)
![x=5000](https://tex.z-dn.net/?f=x%3D5000)
Hence, this year their earnings should be $5000 so that 80% of it which is $4000 will go to school. And 20% which is $1000 will go to costs.
Or we can say last year they earned $4000, so this year they need to earn $1000 more.
b:
The total amount they need to earn this year is $5000.
Salary option 1
salary: $115×52 weeks=$5980
commission: $125,000×0.095=$11,875
total: $5980+$11,875=$17,855
Salary option 2
salary: $450×52 weeks=$23,400
Difference
$23,400-$17,855
=$5545
By rewriting the linear function we will see that the correct option is A.
"an increasing line that passes through (0, 4)"
<h3>
</h3><h3>
Which statement describes the graph?</h3>
Here we have the linear function:
2y = 4x + 8
We can rewrite it to get the function in the slope-intercept form:
y = (4x + 8)/2
y = 2x + 4.
So, the slope is positive, this implies that we will have an increasing line.
We also can see that the y-intecept is 4, this means that the line passes through the point (0, 4).
From that, we can conclude that the correct option is A.

Answer:
![\sf y = -\frac{2}{3}x +490](https://tex.z-dn.net/?f=%5Csf%20y%20%3D%20-%5Cfrac%7B2%7D%7B3%7Dx%20%2B490)
Explanation:
![\sf 2x + 3y = 1470](https://tex.z-dn.net/?f=%5Csf%202x%20%2B%203y%20%3D%201470)
![\sf 3y = 1470 - 2x](https://tex.z-dn.net/?f=%5Csf%203y%20%3D%201470%20-%202x)
![\sf y = \frac{1470 - 2x}{3}](https://tex.z-dn.net/?f=%5Csf%20y%20%3D%20%5Cfrac%7B1470%20-%202x%7D%7B3%7D)
![\sf y = -\frac{ 2x}{3} +\frac{1470}{3}](https://tex.z-dn.net/?f=%5Csf%20y%20%3D%20-%5Cfrac%7B%202x%7D%7B3%7D%20%2B%5Cfrac%7B1470%7D%7B3%7D)

slope intercept form: y = mx + b
where m is slope and b is y-intercept.
