Randall is saving money to buy a bicycle. He has $37.80 in his saving account and saves 20% of his paper route earnings each week. After 10 weeks, he has $87.80 in his saving account. How much does Randall earn each week from his paper route ? A: $25.00
B: $17.56
C: $7.56
D: $5.00

In 10 weeks he saved: 87.8-37.8= $50

so each week he saves 50/10= $5  

Step-by-step explanation:

So every week he earns 5*100 / 20= $25

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.
