Question

After a 70% reduction, you purchase a new soft drink machine on sale for $168. What was the original price of the soft drink machine?

Answer 1

168/.70 = 240

check 240 * .70 = 168 ok

Answer 2

\[\% \Delta = \frac{|a - b|}{a} \times 100\]

a = original price
b = sales price

Answer 3

\[70 = \frac{|a - 168|}{a} \times 100\]
