Answer:
$1,284.
Explanation:
Let the regular price for the set = x
Since the sale offered a 30% discount:
[tex](100\%-30\%)\text{ of x=}$\$899$[/tex]We then solve for x:
[tex]\begin{gathered} 70\%\times x=899 \\ \frac{70x}{100}=899 \\ 70x=89900 \\ x=\frac{89900}{70} \\ x=1284.29 \\ x\approx\$1284 \end{gathered}[/tex]The regular price for the set is $1,284 to the nearest dollar.
