Engineering students at Lancaster College last year received an average of $6,400 in scholarships and grants. This year, the average is $1,344. What is the percent of decrease in the average amount?

79% decrease

Step-by-step explanation:

Subtract 6400-1344=5056

Find percent decrease (5056/6400)x100=79

79% decrease is our final answer

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.

can you rephrase the question ? it is unclear : -)
