Question

What is the percent decrease of $111 and $93

Answer 1

the decrease is 16.22%

Step-by-step explanation

Step 1

you can easily solve and understand this by using a rule of three

Let x represents the new percent

if

`111\Rightarrow100\text{ \%}`

then

`93\Rightarrow x`

as the proportion is the same

`\begin{gathered} (111)/(100)=(93)/(x) \\ \text{cross multiply} \\ 111x=93\cdot100 \\ \text{divide both sides by 111} \\ (111x)/(111)=(9300)/(111) \\ x=83.78 \end{gathered}`

so, $93 is 83.78% of the original price

it means the percent decrease is

`\begin{gathered} \text{Decrease}=\text{original-new} \\ \text{Decrease}=100\text{ -83.78} \\ \text{Decrease}=16.22 \end{gathered}`

Hence, the decrease is 16.22%.
