  • (62/54 - 1)* 100 = X %

    (75/62 - 1)* 100 = Y %

    (81/75 - 1)* 100 = Z %

    Solve and pick the biggest value

  • For Jan/Feb, increase of 8, 8/54=14.8% increase

    For Feb/Mar, increase of 13, 13/62=20.96 % increase

    For Mar/Apr, increase of 6, 6/75=8% increase

    So, Feb/Mar had the biggest increase.

  • biggest percent increase is from Feb to March

    Jan to Feb

    54+54x=62

    54x=8

    x ≈ .1481

    Feb to March

    62+62x=75

    62x=13

    x ≈ .2097

    March to April

    75+75x=81

    75x=6

    x = .08

  • 62 to 75% increase?

  • jan to feb 1/12

    feb to mar 1/13

    mar to apr 1/6

    The answer is march to april with (1/6)*100%
