Answer:

setup cost = $1.75

setup time = 2.625 min

Explanation:

given data

firm operates = 250 days per year

Annual demand = 22,000

Daily demand = 88

Daily production = 250

Desired lot size = 63 (2 hours of production)

Holding cost = $40 per unit per year

to find out

setup cost and setup time

solution

we find first setup cost that is express as

setup cost = $\frac{Q^2*H*(1-\frac{d}{p})}{2D}$ ......................1

here Q is Desired lot size and H is Holding cost and d is Daily demand and D is Annual demand and p is Daily production

put here value

setup cost = $\frac{63^2*40*(1-\frac{88}{250})}{2*22000}$

setup cost = $\frac{2969*40*(0.648)}{44000}$

setup cost = $1.75

and

setup time is

setup time = $\frac{setup\ cost}{setup\ labor}$ ....................2

setup time = $\frac{1.75*60min/hr}{40}$

setup time = 2.625 min

Answer:

Explanation:

For this contract to be enforceable, it must include price, matter and delivery date. These aspects are all best essential and should be included in the contract. From the question when Jaime wrote the contract he failed to detail the price they agreed upon. Even though the rest were included. Therefore this contract cannot be enforced since it is missing this important aspect. Option b is the answer to the question

Rusty Hardware makes only cash sales. It began 2021 with a credit balance of $33,400 in the refund liability account. Sales duri

kompoz [17]

Answer:

$54,400

Explanation:

The balance in the refund liability account would be calculated as;

Ending balance of sales return allowance = Opening balance of allowance + Expected sales return - Actual sales return

Given that;

Opening balance = $33,400

Expected return = $740,000 × 7% = $51,800

Actual return = $30,800

Therefore,

Ending balance of sales returns = $33,400 +$51,800 - $30,800 = $54,400

The balance in the refund liability account at the end of 2021 is $54,400

A company operating under an EOQ policy enjoys rising annual demand for their products for three consecutive years. During this

Oduvanchick [21]

Answer:

Their order quantity will rise but the time between orders will fall.

Explanation:

Let's analyse the EOQ formula:

$Q_{opt} = \sqrt{\frac{2DS}{H}}$

If Demand increases

The dividend increase, so the quotient increase.

EOQ will rise.

<u>Only options b and c are correct on that statment.</u>

Now let's check the time between order:

$\frac{EOQ}{Demand} \times 365$

If we analyze the increase in demand:

√(2xΔDxS/H)/ ΔD

everything else is keep constant so we have:

√(CxΔD)/ ΔDx

If we use L'Hopital we can conclude this function limit is zero.

Anyway a more easy way to do it will be calculate with a demand of 1000

and then with a demand of 50,000 to notice how much the time between order decrease.

√(1000) / 1000 = 0.031622776

√(51000)/ 51000 = 0.004428074

<u>so we have EOQ increase and days between order decrease.</u>

Now only option B is correct !

Spade Agency separates its accounts receivable into three age groups for purposes of estimating the percentage of uncollectible

Natali5045456 [20]

Answer:

The total estimated uncollectible debt is $6000 as computed below

Explanation:

The total estimated uncollectible debt is computed as follows:

Accounts not yet due $25000*4% $1000

Accounts 1-60 days past due $10000*25% $2500

Accounts more than 60 days $5000*50% <u>$2500</u>

Total estimated uncollectible debt <u> $6000</u>

The necessary journal entry to record this estimate is shown below:

Dr bad debt expense $5000

Cr Allowance for uncollectible debt $5000

Even though $6000 is the estimated uncollectible, the implication is that the closing balance in allowance for uncollebtible debt should be $6000,since there is a credit of $1000 already in the account, the balance required to top it up to $6000 is $5000
