Betty's percentage is 15%.
The rate of change is the amount it changes for every missing assignment, therefore it would be -5.
First, add 1 on both sides of the equation to begin to isolate x
x/5 = 8
Now, to isolate x, multiply both sides of the equation by 5/1
· 
= 
= x
x= 7 · 5/1 = 7 · 5 = 35
x = 35
x/5 = 8
Now, to isolate x, multiply both sides of the equation by 5/1
x= 7 · 5/1 = 7 · 5 = 35
x = 35
