Question from virginia, a student: If the sale price is $129.99 @ 70% off - what was the original price? |
Hi Virginia,
If the sale price is 70% off then $\$129.99$ is 30% of the original price. To write this algebraically let $\$P$ be the original price then
\[ \frac{30}{100} \times P = 129.99.\]
Solve for P.
