Answer:
900 large boxes were sold, and 750 small boxes.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of large boxes of cookies sold.
y is the number of small boxes of cookies sold.
A total of 1,650 boxes of Girl Scout cookies were sold last week.
This means that
![x + y = 1650](https://tex.z-dn.net/?f=x%20%2B%20y%20%3D%201650)
So
![x = 1650 - y](https://tex.z-dn.net/?f=x%20%3D%201650%20-%20y)
Each large box cost $3.50 and each small box cost $2.00. The Girl Scout group earned $4,650.
This means that
![3.5x + 2y = 4650](https://tex.z-dn.net/?f=3.5x%20%2B%202y%20%3D%204650)
Since ![x = 1650 - y](https://tex.z-dn.net/?f=x%20%3D%201650%20-%20y)
![3.5(1650 - y) + 2y = 4650](https://tex.z-dn.net/?f=3.5%281650%20-%20y%29%20%2B%202y%20%3D%204650)
![5775 - 3.5y + 2y = 4650](https://tex.z-dn.net/?f=5775%20-%203.5y%20%2B%202y%20%3D%204650)
![1.5y = 1125](https://tex.z-dn.net/?f=1.5y%20%3D%201125)
![y = \frac{1125}{1.5}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B1125%7D%7B1.5%7D)
![y = 750](https://tex.z-dn.net/?f=y%20%3D%20750)
![x = 1650 - y = 1650 - 750 = 900](https://tex.z-dn.net/?f=x%20%3D%201650%20-%20y%20%3D%201650%20-%20750%20%3D%20900)
900 large boxes were sold, and 750 small boxes.
Let's solve this problem step-by-step.
STEP-BY-STEP SOLUTION:
We will be using simultaneous equations to solve this problem.
First we will establish the equations which we will be using as displayed below:
Equation No. 1 -
A + B = 90°
Equation No. 1 -
A = 2B + 12
To begin with, let's make ( A ) the subject in the first equation as displayed below:
Equation No. 1 -
A + B = 90
A = 90 - B
Next we will substitute the value of ( A ) from the first equation into the second equation and solve for ( B ) as displayed below:
Equation No. 2 -
A = 2B + 12
( 90 - B ) = 2B + 12
- B - 2B = 12 - 90
- 3B = - 78
B = - 78 / - 3
B = 26°
Then we will substitute the value of ( B ) from the second equation into the first equation to solve for ( A ) as displayed below:
A = 90 - B
A = 90 - ( 26 )
A = 64°
ANSWER:
Therefore, the answer is:
A = 64°
B = 26°
