Answer:
3.5/1 (or just 3.5)
Step-by-step explanation:
If y = a/n, then the constant proportionality is 3.5/1 or 7/2
Think of this as "rise over run" (we are basically finding the slope)
Percent means parts out of 100
x%=x/100
'of' means multiply
552.5=x/100 times 425
divide bothsides by 425
552.5/425=x/100
multiply both sides by 100
55250/425=x
use calculator
130=x
answer is 130%
