1.) For the animal shelter, Elena purchased five dog leashes for $9.98 each, 1 point five bags of dog food for $24.99 each and five dog crates for x dollars each. Which equation could be used to determine Elena's total cost, C?* A. 5 + $9.98 + 5 + $24.99 = C
B. $9.98 + $24.99/5 =C
C. ($9.98 + $24.99 + x)5 = C
D. 5+ ($9.98 + $24.99 + x) = C

answer:     true

step-by-step explanation:

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.
