Question

original price of oil is 39,95$. discount 32 percent,find the value of the discount, and the final price

Answer 1

discount= $12.784

final price=$27.166

Step-by-step explanation

you can easily solve this by using a rule of three.

Step 1

Let

x represents the discount =32 percent

then

if

`\begin{gathered} 39.95\Rightarrow100\text{ percent} \\ x\Rightarrow32\text{ percent} \end{gathered}`

the proportion is the same, hence

`\begin{gathered} (39.95)/(100)=(x)/(32) \\ \text{solve for x} \\ x=(39.95\cdot32)/(100) \\ x=12.784 \end{gathered}`

Step 2

the final price

`\begin{gathered} the\text{ final price= original price-discount} \\ \text{replacing} \\ The\text{ final price=39.95-12.784=27.166} \end{gathered}`

I hope this helps you
