You purchased a boat for $19,000 and can expect the boat to depreciate at an annual rate of 7.3%. What will the value of your ca
Lerok [7]

Answer:

$14,030.48

Step-by-step explanation:

We can use the following formula to solve:

A=P(1-r)^t

<em>P = principal value </em>

<em>r = rate (decimal) </em>

<em>t = time (years)</em>

<em />

First, lets change 7.3% into a decimal:

7.3% -> \frac{7.3}{100} -> 0.073

Next, plug in the values:

A=19,000(1-0.073)^4

A=14,030.48

The value will be $14,030.48

Assume Jones Manufacturing begins January with 10 units of inventory that cost $10 each. During January, the following purchases
Ratling [72]

Answer:

10.44

Step-by-step explanation:

The weighted average cost per unit method seeks to get the cost of goods sold as an average of all cost of goods in the inventory as at the time of sales.

Part of its objective is to strike a balance between the (FIFO and LIFO) inventory valuation methods.

Beginning inventory ( Jan) = 10 units

Cost of beginning inventory per unit = $10

Total cost of beginning inventory = Cost * Number of units

In this case (10*$10) = $100

Additional purchase (Jan 5) = 8 units

Cost of additional purchase per unit = $11

Total cost of additional purchase = 8 * $11 = $88

Weighted average cost per unit at the time 11 units are sold on January 7 = Total cost of units at that time / number of units available at that time.

= ($100+ $88) / (10+8)

= 188/18

=10.44 (approximated to 2 decimal places)

I hope this helps make the concept clear.

To bill customers for water usage, one city converts the number of gallons used into units. This relationship is represented
-Dominant- [34]

Answer:

g is the independent variable.

u is the independent variable.

Step-by-step explanation:

According to the question, the data mentioned is as follows

Equation g = 748u

where,

g = the total number of gallons of water used

And, u =  the number of units.

As we've seen, Consumers are using the number of units of water.

The volume of water units does not depend on the total quantity of gallons of water that is being used.

So, the number of units i.e u represents an independent variable.

hence,

The value of the total quantity of gallons is entirely dependent on the number of units used, and the g represents the dependent variable

Therefore,

The third and fourth option is correct
