Answer:

Seven.

Step-by-step explanation:

-3-(-8)-(-2)

Using PEMDAS, we are working with only subtraction, which means we will be moving from the left to the right.

Let's start with -3-(-8)

At first it seems like -3-8, which would be -11, HOWEVER, this is incorrect, because it is -8, not 8.

When subtracting a negative number, like we are doing in this problem, it actually turns into addition.

Therefore, -3-(-8) becomes -3+8, which is 5.

After doing this, we have 5-(-2).

Again, we are subtracting a negative number, so in actuality you want to add it.

So instead of 5-(-2), we are actually doing 5+2, which is 7.

Therefore -3-(-8)-(-2) is 7.

Flauer [41]

The cost per unit of the complete units assuming that defective units are sold at Ksh 20 per unit is Rm 93.73.

<h3>What is the cost per unit with defective units?</h3>

The cost per unit with defective units can be computed by subtracting the sales value of the sold defective units from the total production costs, thereby reducing the total production costs, and then dividing the resulting figure by the number of good units.

<h3>Data and Calculations:</h3>

                               Process 1              Process 2          Total costs  

Materials             Rm 100,000              150,000              250,000

Labor                          50,000                50,000              100,000

Overheads                 50,000                20,000                70,000

Total costs                                                                        420,000

Input units = 5,000

Output units = 4,480

Defective units = 520 (5,000 - 4,480)

Sales revenue from defective units = Rm 104 (520 x Rm 0.20)

Cost per unit = Rm 93.73 (Rm 420,000 - Rm 104)/4,480

Thus, the cost per unit of the complete units assuming that defective units are sold at Ksh 20 per unit is Rm 93.73.

Twice a number increased by 5= 2x+5

5 decreased by twice a number= 5-2x

twice the difference of a number and 5= 2(x-5)

Twice the sum of a number and 5= 2(x+5)

Five subtracted from twice a number= 2x-5

Twice a number, less 5= 2x-5
