Let's put it this way: If you plot a few non-x-intercept points and then draw a curvy line through them,you will not know if you got the x-intercepts even close to being correct. <span>The only way you can be sure of your x-intercepts is to set the quadratic equal to zero and solve. So its a matter of guessing from the pictures. Basicaly said, the calculator won't give you the exact result.</span>
Answer:
She has $6,831 in her account by the end of the year.
Step-by-step explanation:
Since there was an increase on Amanda's money of 26.5% the sum she'll have at the end of one year is the amount she had plus the increase, since the amount she had is 100% and it got increased in the value mentioned the final amount is 100% + 26.5% = 126.5% of the original amount. We can solve the question as shown bellow:
final amount = (initial amount)*126.5%
final amount = (initial amount)*(126.5/100)
final amount = 5400*1.265 = 6,831
She has $6,831 in her account by the end of the year.
