North High School is selling tickets to prom. There are two types of tickets. Tickets for the event only are $15 per person (x), and tickets for the event and dinner are $25 per person (y). On the first day of sales, North High School made $1,375. Which equation could be used to help determine the number of tickets sold?

A.) 15x−25y=1,375
B.) 25x−15y=1,375
C.) 15x+25y=1,375
D.) 25x+15y=1,375

option 1

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.
