Answer:
c=12
Step-by-step explanation:
12c - 53= 91
12c=144
c=12
If there only one person then the total would be $40.25
C: (1+3/4)(8) = 14 hours
G: (1+1/3)(8) = 10.7 hours
S: (2/3)(8) = 5.3
The ratio A/r² would represent

which is the circumference of a circle divided by its diameter.
You can see this because the area of a circle is

r² and if you divided that by the radius squared, you are given pi which is the circumference of a circle divided by its diameter.
In a rhombus opposite angles are equal and all 4 add up to 360
assuming one angle is 53, the opposite angle will also be 53 and then adjacent angles will be (360 - (53 x 2))/2 = 254/2 = 127*(deg)
I think the answer you're looking for is 127
