 Math Central Quandaries & Queries
 Question 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.\$
