\dfrac{21}{49}=\dfrac{21:7}{49:7}=\dfrac{3}{7}\\\\\dfrac{21}{49}=\dfrac{15}{h}\to\dfrac{3}{7}=\dfrac{15}{h}\qquad\text{cross multiply}\\\\3h=(7)(15)\\\\3h=105\qquad\text{divide both sides by 3}\\\\\boxed{h=35}\\\\Answer:\ 35\ hours

Target Costing
Lynna [10]

The target cost for Model J20 is $2000.

The required cost reduction is $30.

The total saving will be $30.3.

<h3>How to compute the cost?</h3>

The target cost will be:

= Sales price - (100% × Target cost)

= 400 - (100% × Y)

Y + Y = 400

2Y = 400

Y = 400/2 = 200

Target cost = $200

Therefore, the target cost is $200.

The required cost reduction will be:

= $230 - $200

= $30

The required cost reduction is $30.

The three engineering improvements together will be:

Direct labor reduction = 7.5

Additional inspection = 17

Injection molding = 5.8

Total savings = 30.3

The total savings is $30.3.

Last Year Boris paid £256 for his car insurance This year he has to pay £894 for his car insurance Work out the percentage incre
Agata [3.3K]

Answer:

%∆C = 249.22%

the percentage increase in the cost of his car insurance is 249.22%

Step-by-step explanation:

Given;

Cost of car insurance last year C1 = £256

Cost of car insurance this year C2 = £894

Percentage increase = change in cost/initial cost × 100%

%∆C = ∆C/C1 × 100%

%∆C = (C2-C1)/C1 × 100%

Substituting the given values;

%∆C = (894-256)/256 × 100%

%∆C = 249.21875%

%∆C = 249.22%

the percentage increase in the cost of his car insurance is 249.22%
