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.

Step-by-step explanation:

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
