Question

Of the cars in the parking lot, 20% are silver. If 20% of the cars is 48 cars, what is the total number of cars in the parking lot?

Answer 1

To solve this, we are going to set up a simple rule of three: If 20% are 48 cars, 100% how many cars will be:
$\frac{20----\ \textgreater \ 48}{100----x}$
Now, we can express this as a proportion ans solve for $x$:
$\frac{20}{100} = \frac{48}{x}$
$x= \frac{(100)(48)}{20}$
$x=240$

We can conclude that there are 240 cars in the parking lot.
