A plane flight to Washington D.C costs $200 give or take $50. A plane flight to China costs $1,250 give or take $50. Which plane

kakasveta [241]

Answer:

The DC flight

Step-by-step explanation:

A fixed amount ($50) is always a larger fraction of a smaller number. It is a larger fraction of $200 than of $1250. The plane flight to Washington DC is affected relatively more by a variation of $50.

A price change of $50 on a base price of $200 is a percentage change of 25%. 50/200 × 100% = 25%

A price change of $50 on a base price of $1250 is a percentage change of about 4%. 50/1250 × 100% = 4%

Write the equation of the line in either point-slope form or slope-intercept form.

Inga [223]

Answer:

y = -3x - 0.25

Step-by-step explanation:

Write the equation of a line that has a slope of -3 and passes through the point (1.25, -4).

We'll use the point-slope form of y = mx + b, where m is the slope and b the y-intercept (the value of y when x = 0).

We are told the slope, m, is -3.

y = -3x + b

We need to find a value for b that will cause the line to go through point (1.25,-4), We can do that by entering this point in the equation we have this far:

y = -3x + b

-4 = -3(1.25) + b

-4 = -3.75 + b

-0.25 = b

The equation is: y = -3x - 0.25

Credit sales are collected as follows:65 percent in the month of the sale.25 percent in the month after the sale.10 percent in t

Vitek1552 [10]

Answer:

Step-by-step explanation:

a) November sales = (Total Uncollected Sales - Uncollected Sales from December) / Collection rate after two months

= ($121,100 - $87,300) / 0.20

November sales = $169, 000.00

b) December sales = Uncollected sales from December / Collection rate of the previous month sales,

Therefore: December sales = $87,300 / 0.45 = $194,000

December sales = $194,000.00

c) Each month's collection for the company are:

Collections for ech month = 0.20(Sales from 2 months ago) + 0.25(Last month's sales) + 0.55 (Current sales)

January collections = 0.20($169000.00) + 0.25($194,000.00) + 0.55($132,000)

January collections = $154,900.00

February collections = 0.20($194,000.00) + 0.25($132,000) + 0.55($149,000)

February collections = $153,750.00

March collections = 0.20($132,000) + 0.25($149,000) + 0.55($164,000)

March collections = $153,850.00

Nine more than half of a number is 21

pogonyaev

I assume you're looking for the number:
0.5n + 9 = 21
- 9
0.5n = 12
÷ 0.5
n = 24
So the beginning number is 24, hope this helps!
