Question

3 scale up or scale down to determine each unknown quantity. c \\(\frac{\\$39,000}{1\text{ year}} = \frac{?}{3\text{ years}}\\)

Explanation:

Step1: Identify the relationship

We have a proportion where the ratio of money to years should be constant. So we can set up the equation $\frac{39000}{1}=\frac{x}{3}$ (let $x$ be the unknown amount).

Step2: Solve for x

To find $x$, we can cross - multiply. Multiply both sides of the equation by 3: $x = 39000\times3$.

Step3: Calculate the result

$39000\times3 = 117000$.

Answer:

$\$117,000$
