A ship left a port and headed due west, having 400 pounds of food for the journey's supply. After one day of sailing, 2/5 of the supplies had been used by the sailors in the ship. After another two days of sailing, the sailors used 3/5 of the remaining supplies. Calculate the number of supplies remaining in the ship to last the sailors until they dock.
How many pounds of food supplies were used after one day of sailing? ** After one day of sailing, 2/5*400 = <<2/5*400=160>>160 pounds of food supplies had been used.
How many pounds of food supplies are remaining in the ship? ** The total number of supplies remaining in the ship is 400-160 = <<400-160=240>>240 pounds.
How many pounds of food supplies were used after another 2 days of sailing? ** After another 2 days of sailing, 3/5*240 = <<3/5*240=144>>144 pounds of food had been used.
How many pounds of food supplies are remaining in the ship? ** The total number of supplies remaining in the ship is now 240-144 = <<240-144=96>>96 pounds.
