Answer:

x = -8

Step-by-step explanation:

4x + 2(x - 2) = 4x + x - 12

4x + 2x - 4 = 4x + x - 12

6x - 4 = 5x - 12

6x - 5x = -12 + 4

x = -8

Select the two figures that are sThe tree in your friend's yard casts a shadow that is 27 feet long. Your friend is 5 feet tall
Sphinxa [80]

Answer: 30 ft tall

Step-by-step explanation: X= the height of the tree in feet

27/x = 4.5/5

(4.5)(x) = (27)(5)

(4.5)(x) = 135

divide  by 4.5 to isolate x

135/4.5 = 30

x = 30

the tree is 30 ft tall

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
