lozanna [386]

Answer:

a. increase price in the short run but not in the long run.

Explanation:

The firms don't use resources that are available in limited quantities. So, as firm output increases, they can use resources in higher quantity but at the same price.

Therefore, as quantity demanded increases, the firms can supply higher quantity without any increase in resource cost. So, price increase in short run but not in the long term.

Midyear on July 31st, the Chester Corporation's balance sheet reported:

erastova [34]

Answer:

$76.856 million

Explanation:

As we know that Balance sheet is divided in two portions.

1. Total Assets (Current Assets + Fixed Assets)

2. Total Liabilities and Share Holders' Equity.

and they both should be equal. So we can write from the above information, as:

Total Assets = Total Liabilities + Total Common Stock + Retained Earnings

N.B. We are excluding Cash from our calculation cause we assume that Cash is already been included in Total Assets.

Hence, by putting the values in above equation we can find our Retained Earnings as:

Retained Earnings + $128.230 million + $6.350 million = $211.436 million

Retained Earnings + $134.58 million = $211.436 million

Retained Earnings = $211.436 million - $134.58 million

Retained Earnings = $76.856 million

Longview Hospital performs blood tests in its laboratory. The following standards have been set for each blood test performed:

Julli [10]

Answer:

Instructions are below.

Explanation:

Giving the following information:

Standard:

Direct materials 2.0 plates $2.75 per plate

Direct labor 0.2 hours $15.00 per hour

Variable manufacturing overhead 0.2 hours $7.00 per hour

Actual:

1,500 blood tests.

3,600 plates were purchased for $9,540

3,200 plates were used for blood tests

340 actual direct labor-hours were worked for $5,550

1)The materials price variance:

Direct material price variance= (standard price - actual price)*actual quantity

Direct material price variance= (2.75 - 2.65)*3,600= $360 favorable

2) The materials quantity variance:

Direct material quantity variance= (standard quantity - actual quantity)*standard price

Direct material quantity variance= (2*1,500 - 3,200)*2.75

Direct material quantity variance= $550 unfavorable

3) The labor rate variance:

Direct labor rate variance= (Standard Rate - Actual Rate)*Actual Quantity

Direct labor rate variance= (15 - 16.32)*340= $448.8 unfavorable

4) The labor efficiency variance:

Direct labor time (efficiency) variance= (Standard Quantity - Actual Quantity)*standard rate

Direct labor time (efficiency) variance= (1,500*0.2 - 340)*15

Direct labor time (efficiency) variance= $600 unfavorable

5) The variable overhead efficiency variance:

Variable overhead efficiency variance= (Standard Quantity - Actual Quantity)*Standard rate

Variable overhead efficiency variance= (1,500*0.2 - 340)*7

Variable overhead efficiency variance= $280 unfavorable
