If the unit selling price is $2.50 unit costs $1.00 what is the margin percentage when the unit costs increased &.025
aleksandrvk [35]

Answer:

$3.125

Step-by-step explanation:

Selling Price = $2.50

Unit Cost = $1.00

Gross margin = (Unit cost/Selling price)*100

= (1/2.5)*100

Gross margin = 40%

Unit cost increased by 0.25.

New unit cost = $1.00 1+ $0.25 = $1.25

Selling price =( Unit cost/Gross margin)*100

Selling price =[ (1.25)/40]*100

= 125/40

Selling price = $3.125

Increases the unit selling price to $3.125

Hope this will helpful.

Thank you.

spin [16.1K]

answer:

B. \:  2

explanation:

- x + 8 > 6 \\ subtract \: 8 \: from \: both \: sides \\  \\  - x >  - 2 \\ divide \: both \: sides \: by \:  - 1. \: since  \\   - 1 < 0 \: the \: inequality \: direction  \\  changed. \\  \\ x <  \frac{ - 2}{ - 1}  \\  \frac{ - 2}{ - 1}  = 2 \: can \: be \: simplified \: as \: 2 \: by \\ removing \: the \: negative \: from  \\ numerator \: and \: denominator.  \\  \\ x < 2

The manager of the dairy section of a large supermarket chose a random sample of 250 egg cartons and found that 30 cartons had a
Naya [18.7K]

Answer:

The point estimate for p is of 0.12.

The 90% confidence interval for p is 0.0862 < p < 0.1538.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the z-score that has a p-value of 1 - \frac{\alpha}{2}.

The manager of the dairy section of a large supermarket chose a random sample of 250 egg cartons and found that 30 cartons had at least one broken egg.

This means that n = 250, \pi = \frac{30}{250} = 0.12

The point estimate for p is of 0.12.

90% confidence level

So \alpha = 0.1, z is the value of Z that has a p-value of 1 - \frac{0.1}{2} = 0.95, so Z = 1.645.

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.12 - 1.645\sqrt{\frac{0.12*0.88}{250}} = 0.0862

The upper limit of this interval is:

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.12 + 1.645\sqrt{\frac{0.12*0.88}{250}} = 0.1538

The 90% confidence interval for p is 0.0862 < p < 0.1538.
