WebThe unknown in this problem is the rate or percentage. Since the statement is " (thirty) is (some percentage) of (twenty)", then the variable stands for the percentage, and the equation is: 30 = ( x ) (20) 30 ÷ 20 = x = 1.5. Since x stands for a percentage, I need to remember to convert this decimal back into a percentage: 1.5 = 150%. WebWhen sales increase from 0.8 to 1.4 tons, the company's revenue decreases at an average rate of $200 per ton of goods sold.
