Acar dealer paid a certain price for a car and marked it up byt 7/5 of the price he paid. later he sold it for 24000. what is the original price ?

The original price wil be 10000.

Step-by-step explanation:

Let the original price be x

Let the marked price be given by

so,

According to the question,

so, the original price will be 10000.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
