Answer:
1- The percentage change in the value of the Ecuadorian Sucre was an increase of 400%.
2- The change in the percentage of the value of the Brazilian Real was a decrease of 32.77% of its value.
Explanation:
1- Given that the Ecuadorian sucre (S) suffered from hyper-inflationary forces throughout 1999, and its value moved from S5,000 / $ to S25,000 / $, to determine what was the percentage change in its value, the following calculation:
5000 = 100
25000 = X
25000 x 100/5000 = X
2500000/5000 = X
500 = X
500 - 100 = 400
Therefore, the percentage change in the value of the Ecuadorian Sucre was an increase of 400%.
2- Given that the Brazilian reais (R $) value was R $ 1.80 / $ on Thursday, January 24, 2008, and its value fell to R $ 2.39 / $ on Monday, January 26, 2009, to determine what was the percentage change in its value the following calculation must be performed:
1.80 = 100
2.39 = X
2.39 x 100 / 1.8 = X
239 / 1.8 = X
132.77 = X
132.77 - 100 = 32.77
Therefore, the change in the percentage of the value of the Brazilian Real was a decrease of 32.77% of its value.
