Answer:
Let's start by calculating how much it costs to rent one kart for one hour:
$60 (rental fee per kart) + $15 (hourly fee per kart) = $75 per kart per hour
Since Diddy and Dixie have a total budget of $210 banana coins, they can rent:
$210 ÷ $75 per kart per hour = 2.8 karts per hour
Since they cannot rent a fractional part of a kart, they must round down to 2 karts per hour.
Therefore, with their budget, Diddy and Dixie can rent 2 karts for 1 hour, or 1 kart for 2 hours.
