juan is investing his money. he thinks that he should make $12 for every $100 he invests. how much does he expect to make on an investment of $3200?

Answer

Explanation:

Step1: Set up proportion

Let $x$ be the amount he expects to make. The proportion is $\frac{12}{100}=\frac{x}{3200}$.

Step2: Cross - multiply

$100x = 12\times3200$.

Step3: Solve for $x$

$x=\frac{12\times3200}{100}=12\times32 = 384$.

Answer:

$384$
