A balloon holds 2 cubic feet of air. The balloon is blown up larger to hold 6 cubic feet of air. What is the percent of change for the volume of air inside
the balloon?

Initially 4.2 cubic feet,

Blown to 5.6 cubic feet,

% Change =  (5.6 - 4.2) / 4.2      * 100%

                  = 1.4/4.2 *  100%

                  = 1/3 * 100%

                  = 100/3  %

                   = 33    1/3  %

I hope this helps.
