Answer:
$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 : [tex]0.3*$400000=$120000[/tex]
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: [tex]\frac{1.60-1.50}{1.50} *100=\frac{0.10}{1.50} *100= \frac{2}{30} *100[/tex]% and what in just ratio form is: [tex]\frac{2}{30}[/tex]
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 = [tex]\frac{2}{30} * $120000=$8000[/tex]
