Answer:
11 hours
Explanation:
I divided 18 by 2, finding what it would be if they did equal contributions. Then, I changed both numbers (9 and 9) up/down by 2 (to create an overall difference of 4)- so the work was 11 hours to 7 hours. So, Juby spent 11 hours cleaning.
X = Terrence’s hours
X+4 = Juby’s hours
X + x+ 4 = 18
2X +4 = 18
2X= 14
X= 7. Terrence
X+4 = Juby
7+4 =11 Juby
