Aproportional relationship between the number of pounds of cabbage (x) and the price in dollars (y) is graphed, and the ordered pair (5, 3) is on the graphed line.

The price of 1 pound of cabbage is $0.60

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x ----> the number of pounds of cabbage

y ----> the price in dollars

we have the ordered pair (5,3)

Find out the value of the constant of proportionality k

For x=5, y=3

substitute

----->  

The constant of proportionality k is equal to the unit rate of the proportional relationship

therefore

The price of 1 pound of cabbage is $0.60

step-by-step explanation:

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
