A high school athletic department bought 40 soccer uniforms at a cost of $4,000. After soccer season, they returned some of the uniforms but only received $40 per uniform. What was the difference between what they paid for each uniform and what they got for each return?

$60

Step-by-step explanation:

How much did they pay for each uniform?

$4,000 / 40 = $100

They received upon return $40 for each uniform.

Difference:  $100 - $40 = $60

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
