Hints --- AddTenPercent --- additional step to highlight the math ( number + percentage increase = new total )

I added an extra step to calculate to ADD the Percentage INCREASE onto the int value passed into the formula   ( value + % increase = Total )


        double pct = .10;

        double moreTotal = i * pct;
        double increase = moreTotal + i;

    // Consider this example:   return 123 * 435;
        return increase;
