Let's plug in some numberz!!
And turn words into numberz.
Let x represent laps.
Let y represent total of laps.
Boys ran sixteen laps!!
Girls ran four more laps than boys.
Boys ran 16, so what's 16+4?
Correct, it's 20!!
Our equation is 0.25x = y.
Plug it in!!
What's 0.25 x 20?
Nailed it. It's 5!!
Hope this helped!
