The expression x+2x+(x-4) represents the number of candles Julio sold in three weeks.
Step-by-step explanation:
Let,
x be the number of candles sold by Julio in first week.
According to given statement;
Candles sold in first week = x
He sold twice the number of candles the second week as he did the first week.
Candles sold in second week = 2x
In the third week, Julio sold 4 less than the number he sold the first week.
Candles sold in third week = x-4
Total candles sold = First week + Second week + Third week
Total candles sold = x+2x+(x-4)
The expression x+2x+(x-4) represents the number of candles Julio sold in three weeks.
