How many liters of a 10% solution should be mixed with 60 liters of a 25% solution to get a 15% solution?

120 liters of the 10% solution should be mixed with 60 liters of a 25% solution to  get a 15% solution.

Step-by-step explanation:

Let 'x' be the quantity of 10% solution

Given that we need determine many liters of a 10% solution should be mixed with 60 liters of a 25% solution to  get a 15% solution.

As

10% of x = 0.1x

60 liters of a 25%  = 60 × 0.25

Thus,

The equation becomes

Multiply both sides by 100  

Subtract 1500 from both sides

Simplify

Subtract 15x from both sides

Simplify

Divide both sides by -5

Simplify

Therefore,

unpaid balance is : $149.99-$50 = $99.99 new balance = 149.99+2.62-50 = $102.61 finance charge = 99.99- 0.21/12= $1.75 new balance = 99.99+1.75 = $101.74 average daily balance method average daily balance= 3399.70/30 = $113.32 finance charge = $ 0.21/12ă—113.32 = $1.98 new balance = $149.99-50+1.98 = $101.97

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
