A store sells Brazilian coffee for $10 per lb. and Columbian coffee for $14 per lb. If the store decides to make a 150-lb. blend

Artemon [7]

Answer:

The store should use 112.5 pounds of Brazilian coffee and 37.5 pounds of Colombian cofee.

Step-by-step explanation:

Let "b" be the amount of Brazilian coffee, in pounds, required for the blend and "c" the amount of Colombian coffee required, in pounds.

Since there are two unknown variables a two-equation system is needed to solve the problem, we can set up one equation for weight and another for price as follows:

$b+c=150\\10*b+14*c=11*150$

Solve for "c" by multiplying the first equation by -10 and adding it to the second one:

$b+c=150\\10b+14c -10b-10c=11*150 -(10*150)\\4c=150\\c = 37.5$

Now, solve for b by replacing the value obtained into the first equation

$b+c=150\\b= 150 - 37.5\\b=112.5$

The store should use 112.5 pounds of Brazilian coffee and 37.5 pounds of Colombian cofee.

A store is having a sale on almonds and jelly beans today. The table below shows the amount of each type of food (in pounds) and

Ad libitum [116K]

a. The system of equations are:

3x + 5y = 22

12x + 2y = 25

2. Cost for each pound of almond (x) = $1.5

Cost for each pound of jelly beans (y) = $3.5

<h3>How to Solve a System of Equations?</h3>

From the information given above, we can create the system of equations that will be used in solving the problem as shown below.

a. The system of equations that represents the situation is:

3x + 5y = 22 ----> equation 1

12x + 2y = 25 ----> equation 2

b. Multiply equation 1 by 2, and equation 2 by 5:

6x + 10y = 44 ----> equation 3

60x + 10y = 125 ----> equation 4

Subtract equation 4 from equation 3

-54x = -81

-54x/-54 = -81/-54

x = 1.5

Cost for each pound of almond (x) = $1.5

Substitute x = 1.5 into equation 1

3x + 5y = 22 ----> equation 1

3(1.5) + 5y = 22

4.5 + 5y = 22

5y = 22 - 4.5

5y = 17.5

5y/5 = 17.5/5

y = 3.5

Cost for each pound of jelly beans (y) = $3.5
