The owner of a grocery store wants to mix two types of candy together to make 15 lbs that he he can sell for $5.00 per lb. He wa

Anestetic [448]

Answer:

9 pounds of chocolate and 6 pounds of sugar candies

Step-by-step explanation:

Let's define the variables:

C = pounds of chocolate candies used.

S = pounds of sugar candies used.

We know that he wants to make a total of 15lb, then:

C + S = 15

We also want that the price per pound to be equal to 5$.

This means that the price of the 15 pounds will be the same as the price of the un-mixed candies.

C*$7.00 + $2.00*S = $5.00*15

Then we have a system of equations:

C + S = 15

C*$7.00 + $2.00*S = $5.00*15

To solve this system, we need to start by isolating one of the variables, i will isolate C in the first equation:

C = 15 - S

now we can replace that in the other equation:

(15 - S)*$7.00 + $2.00*S = $5.00*15

Now we can solve this for S.

$105 - $5.00*S = $75

$105 - $75 = $5.00*S

$30 = $5.00*S

$30/$5 = S = 6

Then there are 6 pounds of sugar candy, and we can use the equation:

C + S = 15

C + 6 = 15

C = 15 - 6 = 9

There are 9 pounds of chocolate candy in the mix.

Solve, using the substitution method.

Dafna11 [192]

Hello there!

The question asks us to solve using the substitution method. The equations given are:

$2x+3y=1$

$y=x-8$

We are given a value for y, which is x-8. Substituting $y=x-8$ into the first equation of the system of equation gives us:

$2x+3y=1$

$2x+3(x-8)=1$

Use the distributive property to help simplify and solve for x

$2x+3x-24=1$

Combine like terms

$5x-24=1$

Add 24 to both sides

$5x-24+24=1+24$

$5x=25$

Finally, divide both sides by 5

$x=5$

Now, let's use $x=5$ in the equation $y=x-8$ to find the value of y

$y=x-8$

$y=5-8$

$y=-3$

Now, we have the values x=5 and y=-3. Putting these values into an ordered pair gives us the answer (5,-3), which is the last answer choice.

Let me know if you need any clarifications, thanks!
