Answer:
1. Dave has 23 ($10 coins) and 18 ($20) coins.
2. Dave has 18 ($10 coins) and 16 ($20) coins.
Explanation:
1.
Let x be the number of $10 coins.
Then, the number of $20 coins will be 41-x.
The equation for the sum of money can be written as:
590 = 10x + 20 * (41-x)
590 = 10x + 820 - 20x
590 - 820 = -10x
-230 / -10 = x
x = 23
This means that Dave has 23 $10 coins and (41-23 = 18) 18 $20 coins that sum up to a face value of $590.
2.
Using the same priciple,
let x be the number of $10 coins
let 34-x be the number of $20 coins
Sum of money equation:
500 = 10x + 20 * (34-x)
500 = 10x + 680 - 20x
500 - 680 = -10x
-180 / -10 = x
x = 18
So, Dave has 18 $10 coins and (34-18 = 16) 16 $20 coins that add up to a face value of $500.

Answer:
It helps consumers tell producers when prices are too high.
Explanation:
The law of demand affirms that an increase in price results in reduced demand. It means that when prices increase, consumers will buy fewer quantities of a product or service. The law of demand shows the relationship between price and the quantity of a product consumers are willing to buy in the market.
Consumers can communicate with producers through the volume of products purchased. When the quantity purchased is low, producers will know the set prices are high.
