They can drink 51. Is my answer
Answer: $180
4ft + 5ft + 4ft + 5ft = 18ft
18 x 10 = 180
The answer is 57.5 because 57 represents a whole number and 1/2 equals .5 so 57.5.
People who answer the question will get a thank you!
It would either be 21 or 25 as they both have the same amount of factors :)
