Answer: Sheldon babysat for 6 hours on Saturday.
Step-by-step explanation:
Let x represent the number of hours that Sheldon babysat on Saturday.
He babysat for Saturday and Sunday. If Sheldon babysat for 8 hours on Sunday, it means that the total number of hours that he babysat during the weekend was
(8 + x) hours.
Seldon gets paid $4 per hour to baby sit his cousins. It means that the total amount that he earned during the weekend was 4(8 + x)
He made a total of $56. Therefore,
4(8 + x) = 56
8 + x = 56/4 = 14
x = 14 - 8
x = 6 hours
