A grocer sell 84 oranges in one day. At the end of the day, the grocer has 1/3 as many oranges as he did at the start of the day. If n=the number of oranges the grocer has left at the end of the day, which of the equations could be used to determine the number of oranges left at the end of a day?

Are 84 the number sold or the number he had to sell?

What are your choices?

The number sold

To determine the number of oranges left at the end of the day, we need to set up an equation based on the given information.

Let's assume the number of oranges the grocer had at the start of the day is "x". According to the information provided, at the end of the day, the grocer has 1/3 as many oranges as he did at the start of the day, which means he has (1/3)x oranges left.

We also know that the grocer sold 84 oranges during the day, so we can subtract this from the number of oranges he had at the start of the day. This gives us (x - 84) oranges left.

Putting these two equations together, we have:
(x - 84) = (1/3)x

So, the equation that could be used to determine the number of oranges left at the end of the day is:
x - 84 = (1/3)x
