Given:
Percentage increase = 40%
New price = $56
Let's find the original price.
To find the original price, we have the formula:
[tex]\text{New price = Original price(1 + percentage increase)}[/tex]Let x represent the original price.
Input the values into the formula:
[tex]\begin{gathered} 56=x(1+\frac{40}{100}) \\ \\ 56=x(1+0.4) \\ \\ 56=x(1.4) \\ \\ 56=1.4x \end{gathered}[/tex]Divide both sides by 1.4:
[tex]\begin{gathered} \frac{56}{1.4}=\frac{1.4x}{1.4} \\ \\ 40=x \\ \\ x=40 \end{gathered}[/tex]Therefore, the original price was $40
ANSWER:
$40
