Full solution

50

to

69

?

\newline

Choices:

\newline

(A)

19\%

increase

\newline

(B)

19\%

decrease

\newline

(C)

38\%

increase

\newline

(D)

38\%

decrease

Calculate Difference: Step $1$ : Calculate the difference between the final and initial values. $\newline$ Initial value: $50$ $\newline$ Final value: $69$ $\newline$ Difference = Final value - Initial value = $69 - 50 = 19$
Calculate Percent Change: Step $2$ : Calculate the percent of change. $\newline$ Original amount: $50$ $\newline$ Amount of change: $19$ $\newline$ Percent of change = $(\text{Amount of change} / \text{Original amount}) \times 100\%$ $\newline$ Percent of change = $(19 / 50) \times 100\% = 38\%$
Determine Increase or Decrease: Step $3$ : Determine if it's an increase or a decrease. $\newline$ Since the value increased from $50$ to $69$ , it's an increase.
