I think it’s 5 but don’t get mad if it’s wrong
The correct answer is C) 20 cents.
I got that answer by: 1.60/8=0.20
Hope this helps! =)
Slope-Intercept Form: y=mx+b
Standard Form: ax+by=c
Point- Slope: (y-y1)= m(x-x1)
There are multiple answers to your question-
- If you are only missing b(the y-intercept) but are given a set of points, plug the points into x and y and solve for b.
- If you are only missing the slope(m) but are given a set of points, plug the points into x and y and solve for m.
- If you are given the standard form/point-slope form, change the equation to slope intercept form.
- If you are given an complete form(there is an x and y; no missing variables), but are not sure what it is, plug in some numbers in x to find y, then graph.
3.92
= 1.00 + 1.00 + 1.00 + 0.92
= 100/100 + 100/100 + 100/100 + 92/100
= 300/100 + 92/100
= 392/100

392/100 = 196/50 = 98/25
Hi there!
Your question:
Sales fall from 300 per week to 270 per week what's the percentage change?
My answer:
The formula for calculating percent change is as follows:
[(y2 - y1)/y1]*100=your percent change
y2= first value
y1=second value
Plug the numbers in:
[(300-270)/300]*100
[30/300]*100
0.1*100
10
Therefore, the percent change is 10%
Hope this helps! Let me know if it's incorrect so I can fix it:)
