A market supply is a schedule or curve showing the various amounts of a product that producers are willing and able to make available for sale at each possible price during a specific period.
A market demand plan is a table that shows the relationship between price and demand for a particular commodity. To better understand this relationship, many economists plot a timeline of market demand on a graph called a market demand curve.
The demand plan shows that when the price increases, the quantity demanded decreases and vice versa. These points are plotted and the line connecting them is the demand curve. The product downward slope of the demand curve again indicates the law of demand, the inverse relationship between price and quantity demanded.

Answer:
Explanation:
Let x be the amount loaned at 7% and ($19,000 - x) be the amount loaned at 15%
Given:
Interest incurred at 7%, I1 + Interest incurred at 15%, I2 = $2000
Interest, I = amount × rate
I1 = 7/100 × x
I2 = 15/100 × ($19,000 - x)
From the above expressions,
(0.07)x + (0.15) × ($19,000 - x) = $2,000
Solving for x,
0.07x + 2850 - 0.15x = 2000
Collecting like terms,
0.08x = 850
x = $10625
The amount loaned at 7% interest is
$10625
The amount loaned at 15% interest is ($19000 - $10625)
= $8375
