The list price of a set of golf clubs is $399.99. If the series discount offered is 20/20/15, find the net cost after trade disc

Artemon [7]

Answer:

1,620/.60 = $2,700

step-by-step explanation:

Calculate the complement of the trade discount 100% - 40 = .60 •Calculate the list price $n Discount Rates EXAMPLE: The list price of the office equipment is $15,000. The chain discount is 20/15/10.Step 1. $15,000 X .20 =$3,000Step 2. $15,000-3,000=$12,000 X .15 = $1,800Step 3. $12,000-1,800 = $10,200 X.10 = $1,020Step 4. $10,000- 1,020 = 9,180 Net PriceCalculating Net Price Using Net Price Equivalent Rate EXAMPLE: The list price of office equipment is $15,000. The chain discount is 20/15/10. What is the net price? Step 1. Calculate each rates complement and convert to a decimal.100%-20 = 80% which is .8100%-15= 85% which is .85100% -10 = 90% which is .9Step 2. Calculate the net price equivalent rate. ( Do not round ).8 X .85 X .9 = .612 Net price equivalent rate. For each dollar you are spending about 60 cents.Step 3. Calculate the net price (actual cost to buyer) $15,000 X .612 = $9,180Step 1. Subtract each chain discount rate from 100% (find the complement) and convert each percent to a decimal.Trade Discount AmountList price x Trade discount rate = Trade discount amount $5,678 x 25% = $1,419.50Net Price List price -- Trade discount amount = Net Price

Can anyone tell me what "x" equals. Thx.

Lapatulllka [165]

-6x-1=23

=> -6x=1+23

=> -6x=24

=> x= 24/-6

=> x= -4

Hope it helps!

makkiz [27]

Answer:

a) SE = 25

b) MOE = 41

c) CI = 1951 ; 2049

Step-by-step explanation:

Normal distribution

Population mean unknown

Population standard deviation σ = 350 Kwh

a) The standard error of the mean SE is

SE = σ/√

SE = 350 /√196

SE = 350/14

SE = 25

b) If confidence nterval is 95% or 0,95 then

α = 0,05

And from z table we get z(c) = 1,64

MOE = z(c) * SE

MOE = 1,64 * 350/√196

SE = 1,64 * (350)/14

SE = 41

MOE = And from z tabl we get z(c) = 1,64

MOE = 1,64 * 350/√196

MOE = 1,64 * (350)/14

MOE = 1,64 * 25

MOE = 41

c) The confidence interval is:

Z = 2000

α = 1- 0,95

α = 0,05 ⇒ α/2 = 0,025

CI = Z - z(α/2) * σ/√n ; Z + z(α/2) * σ/√n

z(α/2) from z-table is: z(0,025) = 1,96

CI = 2000 - 1,96* 350/√196 ; 2000 + 1,96* 350/√196

CI = 2000 - 1,96*25 ; 2000 + 1,96*25

CI = 2000 - 49 ; 2000 + 49

CI = 1951 ; 2049
