according to cnn (2016/06/24), the British pound (GBP) crashed to its lowest level as low 1.32/GBP. The exchange rate on June 23rd 2016 was $1.4883/GBP

a)by what % has the Gbp appreciated or depreciated against the dollar during this period?
b)bu what % the US dollar appreciate or depreciate it against the GB the u.s. dollar appreciate or depreciate it against the GBP during this period?
c) if the dollar experienced in appreciation of 15% from June 23rd 201 if the dollar experienced an appreciation of 15% from June 23rd 2016 to the end of 2016 what would the exchange rate be at the end of 2016

a) To calculate the percentage change in the GBP value against the USD, we can use the formula:

Percentage change = ((new value - old value) / old value) * 100

In this case:
Old value = $1.4883/GBP
New value = $1.32/GBP

Percentage change = (($1.32/GBP - $1.4883/GBP) / $1.4883/GBP) * 100

Percentage change = (-0.1683/1.4883) * 100

Percentage change ≈ -11.30%

Therefore, the GBP has depreciated against the USD by approximately 11.30%.

b) To calculate the percentage change in the USD value against the GBP, we can use the same formula:

Percentage change = ((new value - old value) / old value) * 100

In this case:
Old value = $1.4883/GBP
New value = $1/32/GBP

Percentage change = (($1.4883/GBP - $1.32/GBP) / $1.32/GBP) * 100

Percentage change = (0.1683/1.32) * 100

Percentage change ≈ 12.77%

Therefore, the USD has appreciated against the GBP by approximately 12.77%.

c) Assuming the appreciation of the USD against the GBP is 15% from June 23rd, 2016, to the end of 2016, we can calculate the new exchange rate using the formula:

New exchange rate = old exchange rate + (old exchange rate * appreciation percentage)

Old exchange rate = $1.4883/GBP
Appreciation percentage = 15% = 0.15

New exchange rate = $1.4883/GBP + ($1.4883/GBP * 0.15)

New exchange rate = $1.4883/GBP + $0.2232/GBP

New exchange rate ≈ $1.7115/GBP

Therefore, the exchange rate at the end of 2016 would be approximately $1.7115/GBP.

To answer these questions, we can use the following formulas:

a) Percentage change in GBP = [(New exchange rate - Old exchange rate) / Old exchange rate] * 100%
b) Percentage change in USD = [(Old exchange rate - New exchange rate) / New exchange rate] * 100%
c) New exchange rate = Old exchange rate + (Old exchange rate * Percentage change in USD)

Let's solve each question step by step:

a) To calculate the percentage change in GBP:
Percentage change in GBP = [(1.32 - 1.4883) / 1.4883] * 100%
= [-0.1683 / 1.4883] * 100%
= -0.1129 * 100%
= -11.29%

Therefore, the GBP depreciated against the dollar by approximately 11.29%.

b) To calculate the percentage change in USD:
Percentage change in USD = [(1.4883 - 1.32) / 1.32] * 100%
= [0.1683 / 1.32] * 100%
= 0.1275 * 100%
= 12.75%

Therefore, the USD appreciated against the GBP by approximately 12.75%.

c) To calculate the new exchange rate at the end of 2016:
Percentage change in USD = 15% (given)
Old exchange rate = 1.4883

New exchange rate = 1.4883 + (1.4883 * 0.15)
= 1.4883 + 0.223245
= 1.711545

Therefore, if the USD experienced a 15% appreciation from June 23rd, 2016, to the end of 2016, the exchange rate at the end of 2016 would be approximately $1.7115/GBP.
