Answer:
2 contracts
Step-by-step explanation:
Break even point refers to the number of units or sales that needs to be generated for the company to make neither a profit nor a loss.
This means that at the break even point, sales is equivalent to the cost incurred (both fixed and variable).
Let the number of contracts that must be signed to break even be s
The rent is a fixed cost while the cost associated with each contract is variable.
5687.1s = 7000 + 1260.7s
5687.1s - 1260.7s = 7000
4426.4
s = 7000
s = 1.58
≈ 2
She must facilitate 2 contracts each month to break even.
Let us assume the cost of 1 apple = x dollars
Let us also assume the cost of 1 pear = y dollars
Then we can form two equations from the details given in the question. Based on those details the required answer to the question can be easily deduced.
3x + 8y = 14.50
And
6x + 4y = 14
Dividing both sides of the equation by 2 we get
3x + 2y = 7
2y = 7 - 3x
y = (7 - 3x)/2
Putting the value of y from the second equation in the first equation we get
3x + 8y = 14.50
3x + 8[(7 - 3x)/2] = 14.50
3x + 4 (7 - 3x) = 14.50
3x + 28 - 12x = 14.50
- 9x = 14.50 - 28
- 9x = - 13.5
9x = 13.5
x = 13.5/9
= 1.5
Putting the value of x in the second equation we get
6x + 4y = 14
(6 * 1.5) + 4y = 14
9 + 4y = 14
4y = 14 - 9
4y = 5
y = 5/4
= 1.25
So we can find from the above deduction that the cost of 1 apple is 1.5 dollars and the cost of 1 pear is 1.25 dollars
Then
Cost of 2 apples = 2 * 1.5 dollars
= 3.0 dollars
So the cost of 2 apples is $3 and the cost of 1 pear is $1.25.
