Answer: 8 Nights
Explanation:
Cost of a plane ticket to Florida(c) = $1000
cost at the hotel per night (n)
Amount left with Karla after spending on the flight ticket =
$3000-$1000= $2000
To find out how many nights she can stay we should divide the remaining amount she has with (n) = $2000/$250 = 8
Hence Karla can stay for 8 nights
