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 2 329.75
105h + 7.25 5 329.75
7.25h + 105 2 329.75
7.25h + 105 s 329.75

The minimum number of hours that Sara could have worked is 31 hours .

The inequality representation of possible value of h is                               105 + 7.25 h 329.75  

Step-by-step explanation:

Given as :

The earning of Sara in per hour amount = $7.25 per hour

The additional earning of Sara as tips = $105

The Total earning of Sara = $329.75

Let The minimum number of hours that Sara could have worked =  h hours

Now, According to question

The Total earning of Sara = The earning of Sara in per hour amount × minimum working hours + The additional earning of Sara as tips

I.e $329.75 = $7.25 per hour × h + $105

Or, $105 + $7.25 per hour × h = $329.75

Or, $7.25 per hour × h = $329.75 - $105

Or, 7.25 per hour × h = 224.75

∴ h =

I,e h = 31 hours

So, The number of hours Sara worked = h = 31 hours . Answer

Hence, The minimum number of hours that Sara could have worked is 31 hours .

The inequality representation of possible value of h is                               105 + 7.25 h $329.75  

Answer

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
