Answer: % increase ≈ 3433%
Step-by-step explanation:
Step 1: work out the difference (increase) between the tow numbers you are comparing.
Increase = New Number - Original Number
Step 2: Divide the increase by the original number and multiply the answer by 100.
% increase = Increase ÷ Original Number x 100
Step 3: Plug in known values
Increase = 6.18
Original Number = 0.18
% increase = 6.18 ÷ 0.18 x 100
% increase = 34.333... x 100
% increase ≈ 3433%
