Answer:
See below
Step-by-step explanation:
a% of b
= b * a/100 = ab/100
b% of a
= a * b/100 = ab/100
So they are the same.
 
        
             
        
        
        
Solution: f(18.5)=31.47
Step by step solution:
I started by making an equation in slope intercept form- I found the slope, 28/17, with the points (4, 17) and (12.5, 31). Then I found the y intercept, 1, with the point (4, 17). So the equation is y=28/17x+1. Then I just plugged 18.5 where the x is and solved for y
28/17(18.5)+1=y
28/17(37/2)+1=y
1036/34+1= y
30.47+1=y
y=31.47
Keep in mind that 1036/34 is not exactly 30.47 but that 30.47 was rounded to the nearest hundredth
Hope this helps :)
        
             
        
        
        
169.99 / 250 = 0.68 or 68%
100 - 68 = 32% discount
Not sure what asking with total price, because tax varies by state.
        
             
        
        
        
Answer:
D) 35.6
Step-by-step explanation:
Use pythagorean theorem
22^2 + 28^2 = 1268
Take square root of 1268, which equals to 35.60898763.
