A person bought some Australian dollar of NRs 1,50,000 according to the exchange rate. Australian dollar 1 = NRs 77.02. After fi

AlekseyPX

Answer:

5.26% profit (NRs 7,894.24)

Step-by-step explanation:

The exchange of 1,50,000 NRs to A$ will give ...

A$ 1/(NRs 77.02) = x /1,50,000

x = A$ 1,50,000/77.02 = A$ 1947.54 . . . . . (rounded down)

If the Nepali rupees are devalued by 5%, then what did buy A$ 1 will now buy only A$ 0.95. Then the exchange back to NRs will give ...

(NRs 77.02)/(A$ 0.95) = x/(A$ 1947.54)

x = NRs (1947.54)(77.02/0.95) = NRs 1,57,894.24

The effective profit is the difference from the amount initially exchanged, NRs 7,894.24, or ...

(1,57,984.24/1,50,000 -1) × 100% ≈ 5.26%

<em>Additional comment</em>

Except for the loss in the exchange due to rounding down, the profit would be 1/0.95 -1 = 5.2632%. Instead, it is 5.2628%. This is why investors move their money to investments that retain their value when the local currency is losing its value.

Carolyn was asked to solve the following system of equations. Her work is shown. What is the solution to the system of linear eq

Natalka [10]

Answer:

(11, 13)

Step-by-step explanation:

Carolyn's work is incorrect. Below is the correct solution:

Given:

$3x - 2y = 7$ ----› Equation 1

$y = x + 2$ -----› Equation 2

Substitute y = (x + 2) in equation 1

$3x - 2y = 7$ ----› Equation 1

$3x - 2(x + 2) = 7$ (substitution)

$3x - 2(x) -2(+2) = 7$ (distributive property)

[Note: this is where Carolyn made a mistake]

$3x - 2x - 4 = 7$

Collect like terms

$x - 4 = 7$

$x = 7 + 4$ (addition property of equality).

$x = 11$

Substitute x = 11 in equation 2

$y = x + 2$ -----› Equation 2

$y = 11 + 2$ (substitution)

$y = 13$

✅The solution to the system of equations would be:
