Answer:
Cooler - 9.8 hours | Dami - 39.2 hours
Step-by-step explanation:
If Dami works 4 times as much as Cooler, and Cooler works x hours every week, then Dami works 4*x hours every week, or 4x. Since the combined time they work is 49 hours, we can represent this in the equation 4x+x=49, or 5x=49. Dividing both sides by 5 we get x=9.8.
Since Cooler works x hours every week, he worked for 9.8 hours. And since Dami works 4x hours every week, she worked 4*9.8 hours=39.2 hours.
