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:
The correct answer is $2.43.
Explanation:
The annual dividend is $1.90.

Answer:
10.94%
Explanation:
Your father was born 48 years ago
His grandfather deposited $250 in an account for him
Today the money is worth $36,500
The annual rate of his return can be calculated as follows
= 36500/250 ×1/48= (1+r/100)
= 146^0.020833= (1+r/100)
= 1.1094-1
= 0.10940×100
= 10.94%
