If your question is 3(5x -9) then you answer is 15x-27
Step-by-step explanation:
To solve this you have to do 3912/2 which is 1956. Since Thursday is 40 dollars less you have to subtract 40 for Thursday and add 40 for Sunday. So, Thursday brought in 1916 and Sunday brought in 1996. To check your work add 1996 and 1916 and make sure they equal 3912, which they do.
