In this problem, you are given two quantities: 

    - the base value of 4.70%, and

    - the changed value of 5.30%.


They want you calculate the percent of increase.

    |   In this problem it does not matter, what quantities          |
    |      they are and what is their dimension units                |
    | (percents, kilograms, milliliters, cubic meters, amperes etc.) |
    |     All such problems are solved in the same way.              |

    - first you calculate the change of the values, from the basic value to the changed value.

      In this problem this change is  5.30-4.70 = 0.6.



    - then you relate the change value to the base value.

      In this problem this ratio is  .



    - finally, you multiply the ratio by 100 to get the percentage

      In this problem, you get   = 12.76595745%.    ANSWER


You may round the answer in any way you want or in any way as instructed.
