The Plastic Flowerpots Company has two manufacturing departments, molding and packaging. At the beginning of the month, the molding department has 2,000 units in inventory, 70% complete as to materials. During the month, the molding department started 18,000 units. At the end of the month, the molding department had 3,000 units in ending inventory, 80% complete as to materials. Units completed in the molding department are transferred into the packaging department. Cost information for the molding department for the month follows: Beginning work in process inventory (direct materials) $ 1,200 Direct materials added during the month 27,900 Using the weighted-average method, compute the molding department's (a) equivalent units of production for materials and (b) cost per equivalent unit of production for materials for the month. (Round "cost per equivalent unit of production" to 2 decimal places.)

A new backpack at the local store is originally priced $160. It is on sale for 35% off. What is the new sale price?

Answers

Answer:

$104

Step-by-step explanation:

10% = 160 ÷ 10 = $16

5% = $16 ÷ 2 = $8

30 % = 16 x 3 = $48

48 + 8 = $56

$160 - $56 = $104

Hope this helps!

The product of 7/16, 4/3, and 1/2 isa. 7/12.
b. 7/24.
c. 21/32.
d. 2 13/48.

Answers

If you would like to know how much is the product of 7/16,4/3, and 1/2, you can calculate this using the following steps:

7/16 * 4/3 * 1/2 = 7/24

The correct result would be b. 7/24.

$(7)/(16) * (4)/(3) * (1)/(2) = (7* 4* 1)/(16* 3* 2)=(7* 4)/(4* 4* 3* 2)=(7)/(4* 3* 2)\n\n =(7)/(12*2) =\boxed{\bf{(7)/(24)}}$

Your answer is B. 7/24.

1) 2x + 8y = 20
y=2

Answers

Answer:

2x+8y=20;y=2

Solution :

{x,y} = {2,2}

System of Linear Equations entered :

[1] 2x + 8y = 20

[2] y = 2

Graphic Representation of the Equations :

8y + 2x = 20 y = 2

Solve by Substitution :

// Solve equation [2] for the variable y

[2] y = 2

// Plug this in for variable y in equation [1]

[1] 2x + 8•(2) = 20

[1] 2x = 4

// Solve equation [1] for the variable x

[1] 2x = 4

[1] x = 2

// By now we know this much :

x = 2

y = 2

We are done

Solution :

{x,y} = {2,2}
