Jamie has $500 to invest for 3 years. she finds a bank that will invest her money at a simple interest rate of 5%. interest is t is equal to the principal p times the product of the rate r as a decimal and the time d in years. find the amount of interest earned after 3 years.

15% = 0.05
$500 * 0.05 * 3 = $75

 amount of interest earned after 3 years is $75

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.
