Final answer:
The cost of the same dozen roses in Israel, if purchasing power parity holds, is approximately 7.79 Shekels.
Step-by-step explanation:
To find the cost of a dozen roses in Israel, we need to consider the exchange rate between the United States and Israel.
The price of a dozen roses in the United States is $30, so we need to convert this amount to Israeli Shekels using the exchange rate.
According to the given information, $0.2597 can purchase 1.00 Israeli Shekel.
To find the cost in Israeli Shekels, we multiply $30 by the exchange rate:
$30 x 0.2597 = 7.791 Shekels
Therefore, the same dozen roses would cost approximately 7.79 Shekels in Israel.
