Answer:
You will need
280 mL of the 60% solution
and 40 mL of pure alcohol.
Step-by-step explanation:
Let 'x' be the amount of 60% alcohol solution and y the amount of pure alcohol.
Therefore:
(0.6x + y)/320 = 0.65 ⇒ 0.6x + y = 208
x + y = 320
Solving the sistem of equations:
x = 280 and y = 40
Therefore, You will need
280 mL of the 60% solution
and 40 mL of pure alcohol.

Based on the shipping rate and the price of the t-shirts, it can be concluded Sam ordered a total of 6 t-shirts.
<h3>What equation represents Sam's situation?</h3>
5.99 + x12.50 = 80.99
x represents the number of t-shirts she bough, which is the focus of the equation.
Let's solve it:
- 5.99 + x12.50 = 80.99
- x12.50 = 80.99 - 5.99
- x12.50 = 75
- x = 75 / 12.50
- x = 6
<h3>How many t-shirts did Sam order?</h3>
Sam ordered 6 t-shirts.

Answer:
$ 63
Step-by-step explanation:
Let the new price ( price after the discount ) be x.
<u>Old price</u> <u>Discount</u> <u> New price</u>
100 30 70
90 30 x
<u>Now we can make an expression like this to solve this</u>
100 ⇒ 70
90 ⇒ x
<em>Use cross multiplication to solve for x.</em>
100x = 70 × 90
100x = 6300
<em>Divide both sides by 100.</em>
x =<u> $ 63</u>
