Answer:
98 hamburgers were sold on Friday.
Step-by-step explanation:
294/3=98
98+98=196 cheese burgers
196+98=294 hamburgers and cheeseburgers in total
98 hamburgers
-3
You cant count the spaces up (9) and over (-3) between the two points and do up/over so it would be 9/-3 and simplified that is -3/1 or 3
I suggest turning them both into decimals and then multiplying them and turning it back into a decimal
