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:

`(20----\ \textgreater \ 48)/(100----x)`
Now, we can express this as a proportion ans solve for
`x`:

`(20)/(100) = (48)/(x)`

`x= ((100)(48))/(20)`

`x=240`

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