Sandra orders two trucks of water for her pool. The first truck begins filling the pool at a rate of 60 gallons per minute. The second truck arrives 35 minutes later and starts filling the pool at a rate of 80 gallons per minute. Sandra's pool holds 4,200 gallons of water. The equation 60+80(−35)=4,200 models this situation. How many minutes, m, will it take for both trucks to fill Sandra's pool?

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.
