Answer:
The total price is $529.74
Step-by-step explanation:
This question is an example of percentage increase.
To work out the total price you would first have to convert the percentage into a decimal. You can do this by dividing the percentage of 8% by 100, this gives you 0.08. This is because percentages are out of 100.
The next step is to add the value of 0.08 and 1, this gives you 1.08. This is because you are working out the percentage increase.
The final step is to multiply the amount of $490.50 by the value of 1.08, this gives you $529.74. This is because we are finding the percentage increase of 8%.
1) Divide 8 by 100.
2) Add 0.08 by 1.
3) Multiply $490.50 by 1.08.
The value of x is -9 and 3.Option D.
Step-by-step explanation:
Given,
To find the value of x.
We will apply middle term factor formula.
The given equation can be written as,
or, +(9-3)x-27 = 0
or, x²+9x-3x-27= 0
or, x(x+9)-3(x+9)=0
or, (x+9)(x-3) = 0
So, x = -9 and x = 3
Hence,
The correct option is Option D.
