If x oranges were sold on Thursday, what is two times that? Well, 2*x is the same thing as 2x. When a variable and a number a put together, that means it is being multiplied. So, on Thursday x oranges were sold, and on Friday twice as much as that were sold. So, at the bottom, in the red part wold be x and 2x. The blue bar is the total number of oranges sold, which is 108.
108 is the total amount. That’s why it’s the top biggest box. The two smaller boxes make up the total of 108. X is the amount she made on Thursday. 2x is the amount she made of Friday.
