The price of a particular stock is represented by the linear equation , where x represents the number of weeks the stock has been owned and y represents the price of the stock, in dollars. if this relationship continues, what is the price of the stock after it has been owned for 12 weeks?

ANSWER:  

Price of the stock after owning for 12 weeks is $12c, where c can be price per one week.

SOLUTION:

Given, the price of a particular stock is represented by the linear equation where x represents the number of weeks the stock has been owned and y represents the price of the stock, in dollars.  

We need to find the price of the stock when this relationship continues, after it has been owned for 12 weeks?

As it is an linear equation, proportionality exists between x and y

y ∝ x

y = cx → ( 1 )

where, c is the proportionality constant.

Now, put x = 12 weeks to find the y value in (1).

y = c(12)

y = 12c

Hence, price of the stock after owning for 12 weeks is $12c, where c can be price per one week.  

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day
