After finishing her management degree, Jenny started a job with a fixed percentage for an annual raise. Jenny’s annual salary is modeled by the equation A = 100,000(1.065)t where t represents the years she’s been working for the company. Her friend Donald graduated from the same college and started a different job. His annual salary is modeled by the equation A = 85,000(1.07)t. After five years, Jenny has an annual salary of $ , and the difference of Donald’s and Jenny’s salaries is $.

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
