Hi. The cost of a one pound bag is $1.50

To figure this out, you simply divide 2.5 into $3.75

$3.75 ÷ 2.5 lbs = $1.50

You can check your answer by adding the figures:

$1.50 for 1 lb
$1.50 for 1 lb
$0.75 (1/2 of $1.50)
$3.75 Total

Hope this helps.

Take care,
Diana

This is how you find the answer:
Divide 3.75 /2 1/2=1.5
3.75/2.5=1.5

Answer: choice A. 40 liters

====================================

Explanation:

x = number of liters of the 50% alcohol solution

If we have x liters of 50% alcohol, then we have 0.50*x liters of pure alcohol. This is added to 0.90*40 = 36 liters of pure alcohol (from the 90% solution).

So far we have 0.50*x + 36. This expression represents the total amount of pure alcohol. We want a 70% solution, so we want 70% of the total 40+x meaning 0.50*x + 36 is to be set equal to 0.70*(40+x) and we solve for x as shown below

0.50*x + 36 = 0.70*(40+x)

0.50*x + 36 = 0.70*(40)+0.70*(x)

0.50*x + 36 = 28+0.70*x

36 - 28 = 0.70*x - 0.50x

8 = 0.20x

0.20x = 8

x = 8/0.20

x = 40

So that is why the answer is choice A. 40 liters
