Answer:

a. x = 9 + 4y

b. x = (7y-2)/6

c. x = (17 + k)/4

d. x = (9-c)/k

Step-by-step explanation:

In each of the equations, we want to make x the formula subject

a) 3x-12y = 27

3x = 27 + 12y

3x = 3(9 + 4y)

x = 9 + 4y

b) 6x-7y = -2

6x = 7y-2

x = (7y-2)/6

c) 4x - k = 17

4x = 17 + k

x = (17 + k)/4

d) kx + c = 9

kx = 9-c

x = (9-c)/k

A small company is creating a new product to sell to buyers. They have estimated that it will cost them $6 to produce each item
miv72 [106K]

Answer:

$347,600

Step-by-step explanation:

There is fixed startup cost of 242,000 no matter how many units they product.

Also, each unit costs 6 to produce, so to produce 17,600 items, it's going to cost:

17,600 * 6 = 105,600

Along with this the fixed startup cost of 242,000, would make total cost:

Total cost = 242,000 + 105,600 = $347,600
