Answer: Rikshaw bought it for 100. He lost 12% on selling it, so that means he must have sold it for 88. He wants to make 12% profit, so that means he should have sold it at 112.
But we know that he sold it for 2640.
Therefore, if 88 = 2640, 112 would be 2640*112/88 = 3360.
Answer:
Q= 8
The amount emptied is 8 gallons of water
Step-by-step explanation:
First we need to create the equation for the above statement.
Q is directly proportional to the square of d
Q= kd²
Q= 50
d= 5
50= k5²
50 = k25
K = 50/25
K = 2
K is the constant of proportionality.
Now our equation is
Q= 2d²
Where Q = volume in gallons
d = pipe diameters in inch
For a pipe of diameter 2 inch
The amount of gallons of water emptied assuming the same kinf of flow is
Q= 2d²
Q= 2(2)²
Q= 2(4)
Q= 8
The amount emptied is 8 gallons of water

Answer:
8 + 16x
Step-by-step explanation:
Labor time = 4 1/2 hours = 4.5 hours
overhead rate = 95% - mostly dependent on labor
retail price of parts = 134.75
total cost of job = 241.98
241.98 - 134.75 = 107.23
107.25 / (4.5 x 1.95) = 107.25 / 8.78 = 12.22 hourly rate
labor : 12.22 x 4.5 = 54.99
overhead: 54.99 x 95% = 52.24
retail price of parts = <u>134.75</u>
total cost of job: 241.98
