At a sales volume of 34,500 units, Choice Corporation's sales commissions (a cost that is variable with respect to sales volume) total $455,400. To the nearest whole dollar, what should be the total sales commissions at a sales volume of 33,400 units? (Assume that this sales volume is within the relevant range.) (Round intermediate calculations to 2 decimal places.)

$440,880

Explanation:

Sales commission per unit = $455,400/34,500 units

Sales commission per unit = $13.2

Total sales commission at sales volume of 33,400 units:

= $13.2 * 33,400 units

= $440,880

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
