Question

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?

Answer 1

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.
