Answer with Step-by-step explanation:
Gabriella expects to earn $50 in tips during her shift as a waitress today.
In addition to tips, she earns $8.00 an hour.
i.e. she gets $50 as tip and extra $8 for each hour
i.e. if she works for 1 hour she gets $(50+8)
If she works for 2 hour extra she gets $(50+8+8)
Hence, Let she works minimum for x hours to get $114
i.e. 50+8x=114
Subtracting both sides by 50,we get
8x=64
Dividing both sides by 8, we get
x=8
Hence, Gabriella has to work for minimum 8 hours to get $114 tip.
