Find the percent change to the nearest whole percent. from 45 feet to 95 feet.
VMariaS [17]

Answer:

211%

Step-by-step explanation:

To calculate the percentage change between these two numbers we need to divide the end result from the initial starting point. Once we do this we need to multiply the product by 100 to get the percentage value.

95 / 45 = 2.11111

2.11111 * 100 = 211.11%

Finally, we can see that the percentage change from 45 ft. to 95 ft. is 211.11%. If we round this to the nearest whole percent it would be a change of 211%
