Ricardo went jet skiing while on vacation. The jet ski rental cost a flat rate of $20, plus $16.75 per hour. Ricardo had $132.16. How much did he have left after 3 hours of jet ski riding?
$50.25
$61.91
$81.91
$70.25
The cost of the jet ski rental for 3 hours is $20 + 3 * $16.75 = $<<20+3*16.75=65.25>>65.25.
Ricardo had $132.16 - $65.25 = $<<132.16-65.25=66.91>>66.91 left.
Therefore, Ricardo had $66.91 left after 3 hours of jet ski riding. Answer: \boxed{61.91}.
