Frankis investing his money. He thinks that he should make $13 for every $100 he invests. How much does he expect to
make on an investment of $1000

$130

Step-by-step explanation:

Make a proportion

He should make $13 for every $100 invested, and $x for $1000 invested

13/100=x/1000

To solve for x, we need to isolate the variable, x. It is being divided by 100. To reverse this, we need to multiply both sides by 1000

1000(13/100)=(x/1000)1000

The 1000s on the right will cancel, leaving us with

130=x

So, if he invests $100, he should expect to make $130
