Ответ:
25 hours
Step-by-step explanation:
Suppose he works x hours in a week,
In the first job,
charges per hour = $ 7,
So, the total charges for x hours = 7x dollars,
In the second job,
Charges per hour = $ 5,
Also, charges for a week = $ 50
Thus, the total charges for x hours = 50 + 5x
If 7x = 50 + 5x
2x = 50
⇒ x = 25
Hence, he have to work 25 hours for which both jobs pay the same amount.
