Answer:
12.10 out of 58.60 is 20.648464163822524 or 21%
Step-by-step explanation:
work out the difference (increase) between the two numbers you are comparing
Increase = New Number - Original Number
Divide the increase by the original number and then multiply the answer by 100
% increase = Increase ÷ Original Number × 100.
It's a flat horizontal line so the slope is 0
Slope = rise/run = 0/run = 0
The "run" can be any number you want as long as it's not 0.
