jekas [21]3 years ago

Answer:

Step-by-step explanation:

To find f(a), replace x with a:  f(a)=6−1a+15a^2

To find f(a+h), replace x with (a+h):  f(a+h) = 6 -(a + h) + 15(a+h)^2

To find f(a+h)−f(a), expand f(a+h) as given above, and then subtract f(a):

f(a+h)−f(a) = 6 -a - h + 15(a^2 + 2ah + h^2)   -   [6 - a + 15a^2]

                   6 - a - h + 15a^2 + 30ah + 15h^2  -   [6 - a + 15a^2]

This simplifies to:   f(a+h)−f(a) = - h + 30ah + 15h^2

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
