Answer:
c-43=47
Step-by-step explanation:
Well this is kinda obvious.
He already sold 43 cups of hot choclate and he needed 47 more.
So the total amount of cups is (c) so we can make an equation like this
c-43 (since theres total which is unknown so ”c” and then Theres the already sold 43 cups).
c-43=47 (the 47 is the amount he needs to sell)
So final equation to determine total cups needed
c-43=47
