Find the value of y, given value of x

baherus [9]

Answer:

a. y = 2+4.3x when x = -6

substituting value of x, we get

y=2+4.3*-6=2-25.8=23.8

b. y = (x-3)² when x = 9

substituting value of x, we get

y=(9-3)²=6²=36

c. y=x-2 when x = 3.5

substituting value of x, we get

y=3.5-2=1.2

d. y=5x-4 when x = - 2

substituting value of x, we get

y=5*-2-4=-10-4=-14

A company reports cost of goods manufactured of $918,700 and cost of goods sold of $955,448. Compute the average manufacturing c

kirill115 [55]

If the cost of goods manufactured of $918,700 and cost of goods sold is $955,448. The average manufacturing cost per unit assuming 18,374 units were produced is $102 per unit.

<h3>Average manufacturing cost per unit</h3>

Using this formula to determine the average manufacturing cost per unit

Average manufacturing cost per unit= Total cost/Number of units produced

Where:

Total cost=$918,700+$955,448=$1,874,148

Number of units produced=18,374 units

Let plug in the formula

Average manufacturing cost per unit=$918,700+$955,448/18,374

Average manufacturing cost per unit=$1,874,148/18,374

Average manufacturing cost per unit=$102 per unit

Therefore the average manufacturing cost per unit assuming 18,374 units were produced is $102 per unit.
