Q. Find percent change for : a) from

9

to

45

b)

50

to

60

Calculate Change for a): For a) from $9$ to $45$ , first find the change in value. $\newline$ Change = New Value - Original Value $\newline$ Change = $45 - 9$ $\newline$ Change = $36$
Calculate Percent Change for a): Next, calculate the percent change using the formula: $\newline$ Percent Change = $(\frac{\text{Change}}{\text{Original Value}}) \times 100\%$ $\newline$ Percent Change for a) = $(\frac{36}{9}) \times 100\%$ $\newline$ Percent Change for a) = $4 \times 100\%$ $\newline$ Percent Change for a) = $400\%$
Calculate Change for b): For b) from $50$ to $60$ , find the change in value. $\newline$ Change = New Value - Original Value $\newline$ Change = $60 - 50$ $\newline$ Change = $10$
Calculate Percent Change for b): Now, calculate the percent change using the formula: $\newline$ Percent Change = $(\frac{\text{Change}}{\text{Original Value}}) \times 100\%$ $\newline$ Percent Change for b) = $(\frac{10}{50}) \times 100\%$ $\newline$ Percent Change for b) = $0.2 \times 100\%$ $\newline$ Percent Change for b) = $20\%$
