Answer:
14 more hours
Step-by-step explanation:
Since 10% = 0.10 by moving the decimal two spots to the left, we can say that 0.10L is the amount of alcohol with 10% concentration in L liters. Similarly, 0.60L is 60% for L liters and 0.30L is the amount of liters with 30%. If the amount of 10% alcohol solution in liters is x and the 60% in y, we get 0.10x+0.60y=0.30L due to that the liters add up to get a 30% amount of alcohol (this equation represents the amount of alcohol). Next, x+y=L. Since we know that we have 90 liters of 0.60, y=90 and we have
0.10x+54=0.30L
x+90=L. Plugging x+90 for L, we get 0.10x+54=0.3(x+90)=0.3x+27. Subtracting 27 and 0.1x from both sides, we get 0.2x=27. Next, we can multiply both sides by 5 (since 1/0.2=5) to get x=135 liters
Answer:
correct option is A. $46840.50
Step-by-step explanation:
given data
taxable income = $209,150
solution
we calculate the tax for income is $209,150
The tax of the taxable income over $208,850 but but not over $372950 is
tax of the taxable income over $208,850 = $47741.50 plus 33% of the amount over $208850
tax = $47741.50 + 33% of ( $209,150 - $208850 )
tax = $47741.50 + 33% of ( $300)
solve it we get
tax = $46840.5
so correct option is A. $46840.50
