Write your own situation where speed (s) is an independent variable.

step-by-step explanation:

follow pemdas

p - parenthesis

e - exponents

m - multiply

d - divide

a- add

s - subtract

do it in this order and if there's more than one of each work left to right.

answer:

w= 52 and w = 23

step-by-step explanation:

p = -w^2 + 75w - 1200

we want to solve at the break even point, when p=0

0 = -w^2 + 75w - 1200

add 1200 to each side

1200 = -w^2 + 75w - 1200+1200

1200 = -w^2 + 75w

factor out a minus sign from the right side

1200 = -(w^2 -75w)

divide by -1

-1200 = w^2-75w

we will compete the square

-75/ 2 = -37.5   then we square it     (-37.5) ^2 =1406.25

add 1406.25 to each side

1406.25 -1200 = w^2-75w +1406.25

206.25= (w-37.5)^2

take the square root of each side

±sqrt(206.25) = sqrt( (w-37.5)^2)

±sqrt(206.25) =   (w-37.5)

add 37.5 to each side

37.5 ±sqrt(206.25) =   (w-37.5)+37.5

37.5 ±sqrt(206.25) = w

there are two solutions

w =37.5 +sqrt(206.25) = 51.861

w =37.5 -sqrt(206.25)   = 23.139

rounding to the nearest worker

w= 52 and w = 23
