Question

14 Find the percent increase or decrease for each of the following values (indicate whether each is an increase or a decrease). a. 4x to x 75% Decrease b. 0.25m to 0.5m 100% incresse 1 c. 5 2 p to 8P d. y to 0.68y

Answer 1

`\begin{gathered} d\text{. percentage of change=}(Vf-Vi)/(Vi)\cdot100\text{ (Vf=Final value, Vi= Initial value)} \\ (0.68y-y)/(y)\cdot100\text{ (Replacing the values)} \\ (-0.32y)/(y)\cdot100\text{ (Adding like terms)} \\ -0.32\cdot100\text{ (Simplifying)} \\ -32\text{ \% (Multiplying)} \\ \text{The answer is. Decrease of 32\% (As the result was negative) } \end{gathered}`
