Answer:
Step-by-step explanation:
Given

Determine MSE
This is calculated as:
Where:
denominator df
So, we have:
To calculate the df, we have:
--- observations
treatments
So:
So, we have:
The formula in computing the break-even point is:
Break-even = fixed cost / contribution margin
The fixed cost is already given which is $1700 per month. To
compute for the contribution margin, you have to deduct the average cost per
month ($75) to the selling price of each bicycle ($95). The contribution margin
is $20 ($95 - $75).
Substituting the amounts to the formula:
Break-even = $1,700/$20
=
85
Therefore, the store must sell 85 bicycles each month to
break even.
Answer:
5%
Step-by-step explanation:
<u>price after discount :</u>
9 600 - 9 600×40%
= 5760
<u>Original price (price without profit) :</u>
let x be the original price of the device.
x + x × 20% = 5760
Then
x = (5 760×100)÷120
= 4 800
<u>Original price increased by 30% :</u>
4 800 + 4 800×30%
= 6 240
<u>the discount needed to increase the profit by 10% :</u>
[(9 600-6 240)÷9 600]×100
= 35%
Then
to increase the profit by 10% ,we have to reduce
the percent of discount to :
40% - 35%
= 5%
Distribute on the left
-3k+12=48
Then subtract 12 from both sides
-3k=36
Divide both sides by -3
k=-12
Final answer: k=-12
