which of the following situations represent the least percentage of change explain and I'll give BRAINLIEST O Mitch getting a raise from $50,000 to $55,000 a year O A sapling growing from 25 inches to 35 inches in height O An 8-pound puppy gaining 4 pounds in a month A $75 pair of shoes going on sale for $60

Answer 1

(a) the percentage change in the first option is

$\begin{gathered} =\frac{55000-50000}{50000}\times100 \\ =\frac{5000}{50000}\times100 \\ =10 \end{gathered}$

so the change is 10 % in first option.

(b)

$\begin{gathered} =\frac{35-25}{25}\times100 \\ =\frac{10}{25}\times100 \\ =40 \end{gathered}$

change = 40 %

(c)

$\begin{gathered} =\frac{4}{8}\times100 \\ =50 \end{gathered}$

change is 50 %

(d)

$\begin{gathered} =\frac{60-75}{75}\times100 \\ =\frac{-15}{75}\times100 \\ =-20\text{ \%} \end{gathered}$

change is -20 % the negative sign is only showing that it is decreasing.

so the least percentage chage is 10 %

thus answer is option A
