Compute the amount of interest earned in the following simple interest problem. a deposit of $100 at 8% for 20 years =
1160
116.00
1160.00
11,600 00

The amount of interest earned is US$ 160 and none of the alternatives is correct.

Step-by-step explanation:

Let's use the formula for calculating the interest in a simple interest problem, this way:

Interest earned = (Principal * Interest rate * time in years)

Replacing with the real values, we have:

Interest earned = (100 * 0.08 * 20)

Interest earned = 160

The amount of interest earned is US$ 160 and none of the alternatives is correct.

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.
