Answer:

Step-by-step explanation:
we know that
The Susan's hourly wage, must be equal at least to the sum of her monthly household expenses divided by the number of hours worked at month
Remember that

She works 40 hours per week
so


<em>Find out the monthly household expenses</em>
Sum all the expenses
Rent+ Monthly Bills+Entertainment and Food+Savings
substitute the values

Find out the hourly wage

question a is 80
question b 20 (is what I could find but not completely sure)
8/15 x 5/6
•multiply across the numerator and denominator.
= 40/90
• then find a common factor that will go into both the numerator and denominator equally.
Common factor: 5
= 8/18
•there is another common factor, which is 2
Simplified:
=4/9
Answer:
The bottom left answer choice displays an outlier
Step-by-step explanation:
The x coordinate of the vertex = -b/2a = -(-6) / 2*34 = 0.08824
y coordinate = 34(0.08824^2 - 6(0.08824) + 15 = 14.735
so its (0.088, 14.735) correct to 3 decimal places
