7. Lola buys a 1-liter bottle of olive oil. She puts half of the oil in the frying pan. Then she puts of the remaining 1/4 of the oil in a mixing bowl. How much of a liter of oil is
left in the bottle? Illustrate your thinking and your solution.

1/4 L

Step-by-step explanation:

You have one whole liter at first right, so you subtract the hald that you put on the frying pan. After, you subtract the 1/4 that you put in the mixing bowl.

1 - 1/2 = 1/2

1/2 -1/4 = 1/4

=1/4 Liters

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.

cause it equals more
