Answer:
The expression representing the total number of candles Julio sold in the three weeks is
4x -4
Explanation:
Julio sold candles for three weeks.
Let x represent the number of candles he sold the first week.
He sold twice the number of candles the second week as he did the first week. This means that in the second week, number of candles sold
= 2x
In the third week, Julio sold 4 less than the number he sold the in the first week. This means that in the third week, he sold x-4
The total number of candles Julio sold in the three weeks will be
x + 2x + x - 4
= 4x-4
