Hey there!

The answers to your question are C, D, and E

If there are repeats in the X column, then it's not a function. If there are no repeats, then it is! If there are repeats in the Y column, that's ok, but there cannot be repeats in the X column.

Hope this helps! If you need any other help, just tell me!

Soybean mean is 14% protein; cornmeal is 7% protein. How many pounds of each should be mixed together in order to get 280-lb mix
Marianna [84]

I have to form a couple of equations in order to solve it.

let the amount of soybean in the mixture be x and that of cornmeal be y

Step-by-step explanation:

x+y = 280

y = 280 - x

x*(14/100) + y*(7/100) = 280*(12/100)

Multiplying the whole equation by 100;

14x + 7y = 3360

in this equation,put y = 280 - x

14x +7 (280-x) = 3360

14x +1960 - 7x = 3360

14x - 7x = 3360 - 1960

7x = 1400

x = 200lbs

y = 280 - x

= 280 - 200

= 80 lbs

Inorder to make a 280lbs mixture having 12% protein, we should mix 200lbs of soyabean and 80 lbs of cornmeal

Schweser Satellites Inc. produces satellite earth stations that sell for $115,000 each. The firm's fixed costs, F, are $3 millio
ExtremeBDS [4]

The incremental profit is $175,000 and the new situation would obviously have less business risk than the old one.

<h3>Incremental profit</h3>

First step

Profit $600,000

Add Fixed cost $3,000,000

Contribution $3,600,000

Variable Cost=Total Sales−Contribution

Variable Cost=$115,000×50-$3,600,000

Variable Cost=$2,150,000

Second step

Profit at revised cost

Sales $8,625,000

(75x $115,000)

Less: Variable cost $4,350,000

[75×($3,000,000+$500,000/50-$12,000)]

Contribution $4,275,000

Less Fixed cost $3,500,000

($3,000,000+$500,000)

Profit $775,000

Incremental profit=Profit at revised cost-Existing profit

Incremental profit=$775,000-$600,000

Incremental profit=$175,000

Expected rate of return=Incremental profit/Investment

Expected rate of return=$175,000/$4,000,000×100

Expected rate of return=$4.375%

2. Break-even point

Existing

Break-even point=Fixed cost/Contribution

Break-even point=$3,000,000/[($115,000-($3,000,000+$500,000/50)]

Break-even point=$3,000,000/[($115,000-$70,000)

Break-even point= 66.67

Revised

Break-even point=Fixed cost/Contribution

Break-even point=$3,500,000/[($110,000-($3,000,000/50)]

Break-even point=$3,000,000/[($110,000-$60,000)

Break-even point=60
