2. To find 10% from $31.99 you should simply divide $31.99 by ten. Thus, 10% from $31.99 is $3.199.

3. 5% is half of 10%, then 5% from $31.99 is $3.199:2=$1.5995.

$\text{Hello There!}$

$\text{We are going to need to isolate the variable}$

$m - 15 = 20$

$\text{Add 15 to both sides.}$

$\text{We do this because we need to perform inverse operations to find}$ $\text{the value of the variable.}$

$m - 15 + 15 = 20 + 15 = 35$

$\fbox{Therefore, your answer is going to be 35.}$

$\rule{300}{1.5}$
