Question

The 19-unit percent change is -33 %. What is the 12-unit percent change?

Answer 1

SOLUTION:

Step 1:

In this question, we are given the following:

The 19-unit percent change is -33 %.

What is the 12-unit percent change?

Step 2:

From the question, we can see that:

Let x be the unknown percent change

$\begin{gathered} 19\text{ -unit = -33 \%} \\ 12-\text{unit = x} \end{gathered}$

Cross-multiply, we have that:

$\begin{gathered} -33(12)\text{ = 19 x} \\ \text{Divide both sides by 19, we have that:} \\ \text{ x= }\frac{-33(12)}{19} \\ x\text{ =}\frac{-396}{19} \\ \text{x = -20.84 \% ( to 2 decimal places)} \end{gathered}$

CONCLUSION:

The final answer is -20.84% ( to 2 decimal places)
