After a 70% reduction, you purchase a new soft drink machine on sale for $240. What was the original price of the soft drink machine.
Let's assume the original price of the soft drink machine is 'x'.
After a 70% reduction, the sale price of the soft drink machine is 30% of the original price, i.e., 0.3*x.
We're given that the sale price is $240, so we can write the equation:
0.3*x = $240
To find 'x', we can divide both sides of the equation by 0.3:
x = $240 / 0.3
x = $800
Therefore, the original price of the soft drink machine was $800.
