Determine Cove’s break-even point in units and sales dollars. 2. Determine the bakery’s margin of safety if it currently sells 4
swat32

Answer:

a) At break even point, Q = 380 units, Sales dollar = $5247.8

b) Margin of safety at Q = 400 units is 0.05 × 100 = 5

c) Number of cakes that need to be sold before a profit of $2200 is made = 595 cakes

Step-by-step explanation:

Let the number of units be Q

Cost equation = (fixed cost) + (Variable cost)

Fixed Cost = $3898.8

Variable Cost = Variable cost per unit × number of units produced = (2.32 + 1.11 + 0.12) × Q = 3.55Q

Cost equation = 3898.8 + 3.55Q

Revenue = price per unit × number of units sold = 13.81 × Q = 13.81Q

At break even point,

Total cost = Revenue

3898.8 + 3.55Q = 13.81Q

10.26Q = 3898.8

Q = 380 units

In sales dollars, R = 13.81Q = 13.81 × 380 = $5247.8

b) Margin of safety = 100 × (Current sales - Breakeven point sales)/(current sales)

Breakeven point sales = $5247.8

At Q = 400 units, Current sales = 13.81 × 400 = $5524

Margin of safety = 100 × (5524 - 5247.8)/5524 = 5

c) number of cakes that Cove must sell to generate $2,200 in profit.

Profit = Revenue - Total Cost

2200 = 13.81Q - (3898.8 + 3.55Q)

2200 = 10.26Q - 3898.8

10.26Q = 2200 + 3898.8 = 6098.8

Q = 594.4 = 595 units

Find the equation of the tangent line to the graph of f(a) = sec(a) at the point (0, 1).
Paladinen [302]
Let the required equation be y = mx + c; where y = 1, m = f'(0), x = 0
f(a) = sec(a)
f'(a) = sec(a)tan(a)
f'(0) = sec(0)tan(0) = 0

y = mx + c
1 = 0(0) + c
c = 1

Therefore, required equation is
y = 1.

The number -5 is all of the following except
LenaWriter [7]

The correct answer is A. A whole number

Explanation:

In mathematics, whole numbers include numbers that do not include a fraction, for example, the number 4.2 includes a fraction, and therefore it is not a whole number. Moreover, whole numbers include numbers from 0 to infinity but not negative numbers. This means the number -5 is not a whole number because even then this does not include a fraction it is a negative number. According to this, this number is an integer (it does not include fractions), a rational number (it can be expressed as a fraction), and a real number (it can be represented in a line), but not a whole number.
