Answer:
We'll be making 35 liters of 19% glucose.
How much of a 15% solution and a 35% solution do we mix in order to get 35 liters of a 19% glucose solution?
X = liters of 15% and Y = liters of 35%
(.15 X + .35 Y) / 35 = .19
The number of Y liters will equal (35 -X) so the equation becomes
(.15 X + .35 *(35-X) ) / 35 = .19
(.15X + 12.25 -.35X) / 35 = .19
(-.20 X / 35) + (12.25 / 35) = .19
(-.20 X / 35) + .35 = .19
(-.20 X / 35) = -.16
-.20X = -5.6
X = 28 liters of 15% and
Y = 7 liters of 35% glucose
Answer is "c" 28 liters

Answer:
The Total amount of of 33 boxes of chocolates including taxes is $838.358
Step-by-step explanation:
Given as :
The sales tax rate for city = 4.306%
The sales tax rate for the state = 44%
Total number of boxes = 33
The price of each chocolates = $17.13
So , The price of 33 boxes of chocolates = $17.13 × 33
I.e The price of 33 boxes of chocolates = $565.29
Now total tax including state and city = 4.306% + 44% = 48.306 %
So, The tax amount paid for 33 boxes of chocolates = 48.306 % of $565.29
∴ The tax amount paid for 33 boxes of chocolates = 48.306 % × $565.29
= 0.48306× $565.29
= $273.068
∴ The Total amount of of 33 boxes of chocolates including taxes = $565.29 + $273.068 = $838.358
Hence The Total amount of of 33 boxes of chocolates including taxes is $838.358 . Answer
