Morgan wants to sell his bike and does research online to determine what his selling price should be. He finds $25$ bikes of the

same bike model listed, along with their ages, in years, and listed prices, in dollars. He finds the equation of the regression line, shown below, where $p$ represents the predicted price and $y$ represents the age of the bike, in years. $p\ =\ 800\ -\ 50y$

How many ML of a 35% acid mixture and a 95% acid mixture should be mixed to get 120 ML of a 40% acid mixture?
Anon25 [30]

<u>ANSWER: </u>

110ML of 35% acid solution must be mixed with 10ML of 95% solution to obtain 120ML of 40% solution.

<u>SOLUTION:   </u>

First, set up table. fill in the unknowns with variables x and y.  The table is attached below.

From the table shown below, we can easily set up the two equations.  

Sum of values of two acids = Value of mixture  

0.35x + 0.95y = 48  

For convenience, we will multiply the entire equation by 100,

35 x + 95y = 4800     ------ (1)  

Now, Sum of amounts of each acid = Amount of mixture  

x + y = 120    --------- (2)

Multiply eqn 2  with 35 for easy calculation and derive the equation into one variable.

35 = 35x + 35y = 4200  

Subtracting equation (2) from (1),  we get

0 + 60y = 600  

Thus, 60y = 600  

y = \frac{600}{60} = 10

Substituting y = 10 in (2),

35x + 35(10) = 4200  

35x + 350 = 4200  

35x = 4200 - 350  

35x = 3850  

x = \frac{3850}{35} = 110

So, we have x = 110 and y = 10

We can conclude that 110ML of 35% acid solution must be mixed with 10ML of 95% solution to obtain 120 ML of 40% solution.
