The answer is 6.5 Explanation : 1. Find out the increase number by subtracting 4.58 - 4.30 = 0.28 or 6.51% 2. Divide the increase number 0.28 by 4.30 and multiple by 100 which gives you 6.51162791 . 3. Get rid of all the numbers behind 5 and you can’t round it because 1 is too small. Which then gives you the answer 6.5 :) <3
