At what rate does the basin accumulate water? ** 24 gallons in minus 4 gallons out is 24-4=<<24-4=20>>20 gallons per second How long would it take to fill the basin with water? ** 260 gallons divided by 20 gallons per second 260/20 = <<260/20=13>>13 seconds #### 13 $240 was divided between Kelvin and Samuel. Samuel received 3/4 of the money. From his share, Samuel then spent 1/5 of the original $240 on drinks. How much does Samuel have left?
