Treat as fraction
28/4
common factor is 4
divide by 4 or undistribute the 4
7/1
7:1 is simplifed ratio
Answer: A+C=500
7.5A+4.75C=3351.25
C=500-A
7.5A+4.75(500-A)=3351.25
7.5A+2375-4.75A=3351.25
2.75A=976.25
A=355 adults ($2662.50)
C=500-A=145 children ($688.75)
Step-by-step explanation:
Start by finding the slope of the given equation by putting it into slope intercept form (which is y=mx+b). perpendicular lines have slopes that are opposite reciprocals of each other, so if the slope of one line is -1/2, the slope of the like perpendicular to it will be 2/1 (or just 2). your answer (in point slope form) should be: y-6 = -(3/4)(x-2), and you can adjust it if it needs to be in standard form (ax+by=c) or slope intercept form (y=mx+b).
