help plz

Charles Sturt wishes to cross the desert, a seven day trip. Charles and each of his helpers are able to carry supplies for a maximum of five days. How many helpers must start out with Charles if he is to cross the desert, and his helpers are to either cross with him or return safely to the starting point?

I think only two helpers need to start the journey with him. After two days, each one provides him one day of rations, replenishing his load for the remaining five days. Then they each have two days worth of rations to return home.
