Answer:
Gross Pay of Erica is $123.75
Step-by-step explanation:
We are given
Earning per hour = $27.5
Total working hours = 51
we can divide the following as
first 40 hours + 6.5hrs after first 40 hours + 4.5 hours of Sunday
No of hours worked pay per hour
first 40 hours $27.5
after 6.5 hours 27.5 + 13.75 = $41.25 ( 1.5times )
Sunday 4.5hr 27.5 * 2 = $55 (double)
total = 51hrs $123.75
so Erica gross pay of the week is $123.75
The area is given by
A = (5 + 2x) * (10 + 2x) - 50
Rewriting we have:
A = 50 + 10x + 20x + 4x ^ 2 -50
Rewriting we have:
A = 4x ^ 2 + 30x
Substituting the value of the area we have:
54 = 4x ^ 2 + 30x
Rewriting:
4x ^ 2 + 30x - 54 = 0
We look for the roots:
x1 = -9
x2 = 3/2
We take the positive root:
x2 = 3/2
Answer:
the value of x is:
x = 3/2
