Answer:
$3,256.2
Step-by-step explanation:
First, we need to get 3% of 3,460. Find the decimal value of 3%:
3% -> -> 0.03

Now subtract that number from 3,460:
Lastly, lets take the $100 fee off of the number we just got:
The new amount is $3,256.2
Sub in 3 for all the x: =(3)³ - 19(3) +30
Expand the brackets: =27 - 57 + 30
Solve the equation: =0
