Would be appericiate as i am stuck on this question : )

$8000

Step-by-step explanation:

The amount of the total operating expenses attributed to fuel before the increase in fuel price is: 30% of $400000. That is :

Now we need to find out what is the percent increase in fuel if it went from $1.50 to $1.60. We recall that to find the percent increase we need to perform the following calculation: (new price - original price)*100/original price

This gives us: % and what in just ratio form is:

Now, we can estimate how the $120000 fuel cost per year would be affected by such increase by multiplying the percent increase (in ratio form) we just estimated times this annual fuel cost:

Amount that will be added =

Step-by-step explanation:

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
