Henry is starting a t-shirt printing business and plans on selling each shirt for $30, with his cost being $8 per shirt. the equipment will cost $1200.

henry orders 600 shirts and determines that the profit for his new business is modeled by the function p = 22x - 1200. what is the domain of this function in this context?
a) all real numbers
b) {0 ≤ x ≤ 600}
c) {0 ≥ x ≥ 600}
d) {-1,200 ≤ p ≤ 2,000}

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.
