Question

A certain container of mouthwash usually costs $2.99. If it was on sale for 20% off , how much does the mouthwash cost now

Answer 1

Given Data:

The cost of the mouthwash is: P=$2.99

The sale discount of the mouthwash is: d=20%

The expression to calculate the sale discount price of the mouthwash is,

`\begin{gathered} s=P*(100-d)/(100) \\ s=2.99*(100-20)/(100) \\ s=2.99*(80)/(100) \\ s=2.99*0.8 \\ s=2.392 \end{gathered}`

Thus, the new price of the mouth wash is $2.392.
