'' aluminum can pull tabs collected by students''

class number of pull tabs collected

boys 65
girls 72

the environment club collected pull tabs from aluminum drink cans to raise money. their goal was to collect 175 pull tabs. which equation can be used to find the number of pull tabs (p) needed to reach their goal.
(a) 175 - 65 = p
(b) 175 + 65 = p
(c) 175 - 137 = p
(d) 175 + 137 = p

C

Step-by-step explanation:

Since the boys have collected 65 tabs and girls have collected 72,they have a total of 137. Their goal is 175, so they need to subtract the amount they have from the amount they need, which is 175-137 (C)

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.

the answer is 48m^2!
