To find the percentage change in the value of the dollar relative to the yen, we can use the formula:
Percentage change = ((new value - old value) / old value) * 100
Using the values given in the question, we get:
Percentage change = ((123 - 262) / 262) * 100
Percentage change = (-139 / 262) * 100
Percentage change = -53.05%
This means that the value of the dollar decreased by about 53% relative to the yen. The closest choice to this is B, which says that the value decreased by about 50%.
