Final answer:
The equation to find the total number of cups of hot chocolate Will must sell to buy the snowboard is c + 50 = 95, where c is the total number of cups.
Step-by-step explanation:
The question involves determining the equation that represents the total number of cups of hot chocolate Will needs to sell to buy a snowboard. Will has already sold 50 cups and needs to sell 45 more. So, we are looking for the total number of cups Will must sell. If we let c be the total number of cups he must sell, then the equation is simply the initial 50 cups sold plus the remaining 45 cups needed to reach his goal. Therefore, c + 50 = 45 + 50, simplifying that gives us c = 95.
To find the total number of cups Will must sell to buy the snowboard, we can use the equation c - 50 = 45.
To solve for c, we add 50 to both sides of the equation, which gives us c = 95.
So, Will must sell a total of 95 cups to buy the snowboard.
