Gabriella expects to earn $50 in tips during her shift as a waitress today. In addition to tips, she earns $8.00 an hour. If she wants to make at least $114 today, how many hours must she work at a minimum?

Respuesta :

she must work at least 8 hrs

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.
