Question

A winter jacket is marked down 75% from its original price. According to the new price tag, it now costs $52.50. What was the original price?

Answer 1

mark down of 75% means you pay 25%

then 25% = $52.50

4 x 25% = 4 x $52.50

100% = 210

Answer 2

\[\LARGE x(1-75\%)=52.50\]
\[\LARGE x(1-\cfrac{75}{100 })=52.50\]
\[\LARGE x-\cfrac{75x}{100 }=52.50\]
\[\LARGE \frac{100x}{100}-\cfrac{75x}{100 }=52.50\]
\[\LARGE \frac{25x}{100}=52.50\]
\[\LARGE \frac{x}{4}=52.50\]
can you do it now ? :)
