Question

Ryan estimates the measurements of the volume of a container to be 36 cubic inches. the original volume of the popcorn container is 40 cubic inches.
Part A: find the difference

Part B: Find the percent of change

Answer 1

Answer:

• difference: -4 cubic inches
• % change: -10%

Step-by-step explanation:

The difference between the new volume and the original volume is ...

  (new volume) - (original volume) = (36 in³) - (40 in³) = -4 in²

__

The percentage change is figured with respect to the original volume:

  % change = (difference)/(original volume) × 100% = (-4 in³)/(40 in³) × 100%

  = -1/10 × 100% = -10%
