The RideEm Bicycles factory can produce 140 bicycles in a day at a total cost of $10,600. It can produce 160 bicycles in a day at a total cost of $11,400. What are the company's daily fixed costs (in dollars)

Fixed costs= $5,000

Explanation:

To calculate the fixed costs, we need to use the high-low method.

Variable cost per unit= (Highest activity cost - Lowest activity cost)/ (Highest activity units - Lowest activity units)

Variable cost per unit= (11,400 - 10,600) / (160 - 140)

Variable cost per unit= $40

Fixed costs= Highest activity cost - (Variable cost per unit * HAU)

Fixed costs= 11,400 - (40*160)

Fixed costs= $5,000

Fixed costs= LAC - (Variable cost per unit* LAU)

Fixed costs= 10,600 - (40*140)

Fixed costs= $5,000

start by isolating the variable on one side by adding 43w^2 to both sides.   the equation will read:

25w^2+5=0

*subtract 5 from both sides*

25w^2=-5

*divide both sides by 25*

w^2=-1/5

*take the square root of both sides*

w=√(-1/5)

the square root of -1 is i.   the square root of 5 remains √5

the answer is i/√5.

hope this
