The edges on Josiah's snowboard are chipped and dented from riding over rocks, so Josiah wants to buy a new one. He can't afford the board he wants, so he opens a hot chocolate stand near his house. Josiah figures out how many cups of hot chocolate he must sell to have enough money for the snowboard. One cold, snowy Saturday, Josiah sells 43 cups of hot chocolate. Now, he needs to sell 47 more cups to buy the snowboard.
Which equation can you use to find the total number of cups c Josiah must sell to buy the snowboard?
43c=47
c+43=47
c/43=47
c-43=47
