A dress was reduced in price by $19.56. This was 20% of the original price. Find the sale price

Sagot :

Let:

x = Original price

xs = Sale price

1st, express the percentage as a decimal:

20% = 20/100 = 0.2

[tex]\begin{gathered} x\cdot0.2=19.56 \\ x=\frac{19.56}{0.2} \\ x=97.8 \end{gathered}[/tex]

Therefore, the sale price will be:

[tex]\begin{gathered} xs=x-19.56 \\ xs=97.8-19.56 \\ xs=78.24 \end{gathered}[/tex]

Answer:

$78.24
