Adam has $450. He spends $210 on food. Later he divides all the money into four parts out of which three parts were distributed and one part he keeps for himself. Then he found $50 on
the road.

$110

Step-by-step explanation:

Adam would have $110. Subtract 210 from 450 to get how much money he has after shopping for food. 450 - 210 = 240. Divide 240 by 4 because he distributed his money into 4 parts. 240 / 4 = 60. He keeps one fourth of the 240, so he keeps $60. He finds $50 on the road, so 40 + 50 = 110. He has $110 in the end.

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.
