The answer is 1/3, I just answered this on USATP.
A market economy primarily aims to efficiently meet consumer demand for goods and services, foster healthy competition amongst suppliers, and promote private enterprise, rewarding individuals for their ability to produce goods and services that society values.
The goal of a market economy firstly is to coordinate a process where firms aim to produce goods and services in the quantity, quality, and price that consumers want, making efficient use of resources. Secondly, it is designed to create an environment where competition amongst suppliers can take place, aiming to offer the best goods and services at the lowest prices, stimulating productive efficiency. Lastly, market economies are based on the principle of private enterprise, where personal income is driven by an individual's capacity to convert resources, particularly labor, into a product or service that society values.

Answer:
14 units
Step-by-step explanation:
To find the length of the other leg of a right triangle, where one leg is 7 units long and the hypotenuse is 16 units long, use Pythagoras Theorem.
Pythagoras Theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the legs.
Let the legs of the right triangle be "a" and "b", and the hypotenuse be "c". Therefore:
Therefore, the length of the other leg is 14 units (rounded to the nearest whole number).

Step-by-step explanation:
B $3000
C $5000
D $3500
Answer: A $4000
Step-by-step explanation:
Let x represent the amount which he invested at 3% interest.
Let y represent the amount which he invested at 3.25% interest.
Walt made an extra $7000 last year from a part-time job. He invested part of the money at 3% and the rest at 3.25%. This means that
x + y = 7000
The formula for determining simple interest is expressed as
I = PRT/100
Considering the account paying 3% interest,
P = $x
T = 1 year
R = 3℅
I = (x × 3 × 1)/100 = 0.03x
Considering the account paying 3.25% interest,
P = $y
T = 1 year
R = 3.25℅
I = (y × 3.25 × 1)/100 = 0.0325y
He made a total of $220.00 in interest., it means that
0.03x + 0.0325y = 220 - - - - - - - -- -1
Substituting x = 7000 - y into equation 1, it becomes
0.03(7000- y) + 0.0325y = 220
210 - 0.03y + 0.0325y = 220
- 0.03y + 0.0325y = 220 - 210
0.0025y = 10
y = 10/0.0025
y = 4000
