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:
126,000
Explanation:
56,000/4 = 14,000
5*14,000 = 70,000
56,000 + 70,000 = 126,000
Answer:
A. $19,034
Explanation:
The computation of the present value for 20 years cash flow is shown below:
For the First 10 years
Given that
Payment for first 10 years = $2,000
Discount rate = 11%
Now the present value is
= $2000 ÷ 1.11 + $2,000 ÷ 1.11^2 +...........+ $2,000 ÷1.11^10
= 11,778.46402 ..............(1)
For the Next 10 years
Given that
Payment for next 10 years = 3,500
Discount rate = 11%
Now the present value is
= $3,500 ÷ 1.11 + $3,500 ÷ 1.11^2 +...........+ $3,500 ÷ 1.11^10
= 20,612.312
So, today present value is
= $20,612.312 ÷ 1.1110
= 7,259.339 ...........................(2)
Now
Total present value is
= $7,259.339 + $11,778.46402
= $19,034
