GIven the statement:
Sally's huge dog weighed 145 pounds in 2006 and then weighed 175 pounds in 2018.
Determine the rate of change.
Solution:
In order to determine the rate of change we simply need to subtract the final weight by the initial weight, then we divide the difference by the initial weight.
= 175 pounds - 145 pounds
= 30 pounds
= 30 pounds/ 145 pounds
= 0.2069
Since we are given a decimal answer, in order to convert it into percentage, we multiply the decimal by 100. Hence, in converting a percentage into decimal, we divide the percentage by 100.
= (0.2069)(100)
= 20.69%
Final answer:
The rate of change is 20.69%
