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.

Answer 1

Answer:

90% increase.

Step-by-step explanation:

Percent change in altitude = (difference in altitude * 100) / original altitude

= (95-50) * 100 / 50

= 90%.

Answer 2

Answer:

Percent of change in altitude = 90 %

Since the altitude increases from 50 ft to 95 ft the change is positive.

Step-by-step explanation:

Initial altitude, = 50 ft

Final altitude, = 95 ft

Increase in altitude = 95 - 50 = 45 ft

Percentage increase

              $=\frac{45}{50}\times 100=90\%$

Percent of change in altitude = 90 %

Since the altitude increases from 50 ft to 95 ft the change is positive.
