-6 2/7 + 3 1/14 = 3 3/14 <--- repeating decimal.

A chef is going to use a mixture of two brands of Italian dressing. The first brand contains 9% vinegar, and the second brand co
kobusy [5.1K]
So, the first brand has 9% vinegar, and say we use "x" amount of it, then, the amount of vinegar in "x" is 9% of x, or (9/100) * x, 0.09x.

the second brand has 14% of vinegar, and if we use say "y" amount of it, then the amount of vinegar in "y" is really just 14% of "y" or, (14/100) * y, 0.14y.

\bf \begin{array}{lccclll}&#10;&\stackrel{mL}{amount}&\stackrel{\%}{concentration}&\stackrel{amount}{concentration}\\&#10;&------&------&------\\&#10;\textit{first brand}&x&0.09&0.09x\\&#10;\textit{second brand}&y&0.14&0.14y\\&#10;------&------&------&------\\&#10;mixture&230&0.13&29.9&#10;\end{array}

so, whatever "x" and "y" are, we know that x + y = 230.

and we also know that their concentration amounts will also add up,  0.09x + 0.14y = 29.9.

\bf \begin{cases}&#10;x+y=230\implies \boxed{y}=230-x\\&#10;0.09x+0.14y=29.9\\&#10;----------\\&#10;0.09x+0.14\left(\boxed{230-x}  \right)=29.9&#10;\end{cases}&#10;\\\\\\&#10;0.09x+32.2-0.14x=29.9\implies -0.05x=-2.3\implies x=\cfrac{-2.3}{-0.05}&#10;\\\\\\&#10;x=46

how many milliliters will it be for the second brand?  well, y = 230 - x.

patriot [66]

Answer:

See Explanation

Step-by-step explanation:

According to the Question,

Given that, A retired couple has up to $50,000 to invest. As their financial adviser, you recommend that they place at least $35,000 in Treasury bills yielding 1% and at most $10,000 in corporate bonds yielding 3%.

Therefore,

Let, x be the amount of money invested in Treasury bills

y be the amount invested in corporate bonds

Thus, the system of equations of linear inequalities is

x + y ≤ 50000

x ≥ 35000

0 ≤ y ≤ 10000

For, the graph of the system of equations of linear inequalities describes the possible amounts of each investment.
