from Gracie: If you buy something for $\$6.30$ and it’s 30% off what was the original price? |
Hi Gracie,
Since $\$6.30$ is the result of subtracting 30% from the original price, $\$6.30$ is 70% of the original price. To say this with an equation let $P$ be the original price in dollars then $0.70 \times P = 6.30.$
Solve for $P.$
