Question

Find the percent of change in altitude if a weather balloon moves from 50 ft to 95 ft. Describe the percent of change as an increase or decrease. Round to the nearest tenth if necessary.
A. 90%; increase

B. 55.9%; decrease

C. 90%; decrease

D. 76.5%; increase

Answer 1

The change of the weather balloon would be 90% increase. to get the percentage of change we have to subtract 50 ft to 95 ft, it will then give us the 45 ft change. Then we have to divide 45 ft by 50 ft times 100, it will give us 90%. Then since the change and percentage of change is positive then the change could be describe as increasing.
