Answer (2)

Multiply the amount in PGK by the conversion rate.
Perform the calculation: 500 × 0.45 = 225 .
PGK500 is equivalent to USD225.
The answer is 225 ​ .

Explanation

Understanding the Problem We need to find out how much PGK500 is worth in US dollars, given that PGK1.00 is equivalent to USD0.45. This is a straightforward conversion problem.

Performing the Conversion To convert PGK500 to US dollars, we multiply the amount in PGK by the conversion rate: U S D = PG K × C o n v ers i o n R a t e U S D = 500 × 0.45

Finding the Equivalent Amount Calculating the result: U S D = 225 So, PGK500 is equivalent to USD225.

Stating the Answer The correct answer is C. 225


Examples
Imagine you are traveling from Papua New Guinea to the United States and you want to exchange PGK500 to US dollars. Knowing the exchange rate is crucial. If PGK1 is worth USD0.45, then PGK500 would be worth USD225. This conversion helps you understand how much money you will have in the local currency, allowing you to budget effectively for your trip.

Approximately 2.81 × 1 0 21 electrons flow through the device delivering a current of 15.0 A for 30 seconds. This is calculated by first determining the total charge in coulombs and then dividing it by the charge of a single electron. Consequently, the total charge provided is 450 C, leading to the final count of electrons.
