Discount on LCD TV is $240.<br><br> Sale Price is $1575.00<br><br> What was the list price?
Vikki [24]

Answer:  The list price was $1815.00.  

Step-by-step explanation:  Given that the discount on a LCD TV is $240 and the sale price is $1575.00.

We are to find the list price.

The discount is given on the price that is listen on the LCD TV.

So, the list price will be equal to the sum of the sale price and the discount price.

Therefore, the required list price of the LCD TV is given by

L.P.\\\\=\textup{sale price}+\textup{discount}\\\\=\$(1575.00+240.00)\\\\=\$1815.00.

Thus, the list price was $1815.00.

Mrs. Kemp began the school year with 20 students in her kindergarten class. She had 23 students at the end of the year. What was
Liula [17]
First, we’re going to use this formula:

2nd number - 1st number
————————————— x 100%
1st number


If we plug in the numbers to this equation:

23-20
———- x 100%
20

And subtract 23 to 20, the answer to this equation is:

3
—- x 100% = 15%
20

In this case, the percent of increase is 15%.

If I make 11.50 an hour working full time (40 hours a week) how much money do i make a year after deducting 60 dollars of taxes
Kazeer [188]
Given:
hourly rate = 11.50
hours worked in a week = 40 hours
taxes per moth = 60

Every month may be 4 weeks or 5 weeks but we know that 1 year has 52.1429 weeks.

Let us compute for the whole year:

Earnings:
11.50 /1 hour * 40 hours/1week * 52.1429 weeks/1year  
= 11.50 * 40 *  52.1429/year
= 23,985.734 per year

Taxes:
60 / per month * 12 months / 1 year
= 60 * 12/year
= 720 per year

Net earning per year
23,985.734 - 720 = 23,264.734 

Net earning per month
23,264.734 ÷ 12 months = 1,938.81 

You will earn 23,264.73 annually from a monthly earning of 1,938.81

Which graph represents y=1/2x+2 <br><br> please help!!
wel

Answer:

B

Step-by-step explanation:

Let’s first look at the y-intercept. Since the equation is in y = mx + b form, we know that m is the slope and b is the y-intercept, so the slope is 1/2 and the y-intercept is 2, or (0,2). We can narrow down our search by noticing that C and D don’t intersect (0,2). That leaves A and B.

The slope is calculated by (y_1 - y_2)/(x_1 - x_2) given points (x_1, y_1) and (x_2, y_2). The slope for A is (4-0)/(2-(-2)) = 4/4 = 1 and the slope for B is (2-0)/(0-(-4)) = 2/4 = 1/2. The slope of B matches the slope that we are looking for. So, the answer is B.
