Let
the original price = a
60% of the original price can be expressed as follows
[tex]\begin{gathered} \frac{60}{100}\times a=24 \\ \frac{3}{5}a=24 \\ \text{cross multiply} \\ 3a=24\times5 \\ 3a=120 \\ \text{divide both sides by 3} \\ a=\frac{120}{3} \\ a=40 \end{gathered}[/tex]The original cost of the dress is $40. The equation can be represented as follows
0.6a = 24
