Add all the numbers then divde by how many numbers there are so the total divde by 8
Answer:
x = 4 or x = 12
Step-by-step explanation:
Given:
y = -10x² + 160x - 430
When y = $50
50 = -10x² + 160x - 430
50 + 430 = -10x² + 160x
480 = -10x² + 160x
-10x² + 160x - 480 = 0
Divide through by -10
x² - 16x + 48 = 0
Solve the quadratic equation using factorization method
+48 = -12 × -4
-16 = -12 -4
Therefore,
-12 and -4 are both factors
x² - 16x + 48 = 0
(x - 4 )(x - 12 ) = 0
x - 4 = 0
x = 4
OR
x - 12 = 0
x = 12

Answer:
you don't save any money, you lose money instead
Explanation:
Given,
At 54, there is a tax rate of 28%
At 59½ there is a penalty of 10% with the tax rate of 28%
Therefore at 54, money left after tax = $45000*(1-0.28)=45000*0.72=$32400
At 59½, money left after tax =$45000*(1-0.10)*(1-0.28)= 45000*0.90*0.72=$29160
Money lost =29160-32400= -$3240
