Answer:

Explanation:

Block on the table m(A) = m1,

block on the cord m2,

the coefficient of static friction is k1=0.4,

the coefficient of kinetic friction is k2 =0.28

(a)

Block A:

T = F(fr) = k1 •N = k(s) • m1 •g,

Block B: T = m2•g.

k1 • m1 •g= m2•g,

m1 = m2/k(s) = m2/0.4.

(b)

Block A:

T = F(fr) = k2 •N = k2 • m1 •g,

Block B:

T = m2•g.

k2• m1 •g= m2•g,

m1 = m2/k2 = m2/0.28.

Variable cost = Variable Manufacturing Expenses + Variable Selling & Administrative Expenses

Total Contributiom Margin= $924,000 - $462,000

Total Contributiom Margin= $462,000

Now let calculate Unit Contribution Margin using this formula

Unit Contribution Margin= Total Contribution Margin/Total number produced and sold cement

Let plug in the formula

Unit Contribution Margin = $462,000 / 220,000 Unit Contribution Margin= $2.10 per unit

Therefore the Unit Contribution Margin will be $2.10 per unit
