Sara earned $7.25 per hour plus an additional $105 in tips waiting tables last week. she earned at least $329.75. if h represents the minimum number of hours that sara could have worked, which inequality represents all the possible values of h?
a) 105h + 7.25 ≥ 329.75
b) 105h + 7.25 ≤ 329.75
c) 7.25h + 105 ≥ 329.75
d) 7.25h + 105 ≤ 329.75

7.25 (h)  + 105 ≥   329.75    represents all the possible values of h.

Step-by-step explanation:

Sara's earning per hour = $7.25

Amount earned in tips = $105

Total amount she earned = $329.75

h  :  Minimum number  of hours Sara could worked

So, according to the question:

Total amount earned by Sara in h hours =

Amount each hour x h working hours + Tip

= 7.25 (h)  + 105

And the earned amount id more than on equal to $329.75

⇒7.25 (h)  + 105 ≥   329.75  is the required inequality which represenst all possible values of h.
