You buy certain supplies in Nearland. Last year, the currency exchange rate was 1 USD = 3 NRD. Are these supplies more or less expensive to buy now than last year? Explain your answer in complete sentences.

To determine if the supplies are more or less expensive to buy now compared to last year, we need to consider the current currency exchange rate between USD and NRD. If the current exchange rate is lower than 1 USD = 3 NRD, then the supplies would be more expensive to buy now than last year. Conversely, if the exchange rate is higher than 1 USD = 3 NRD, then the supplies would be less expensive to buy now than last year. It's important to check the current exchange rate to make an accurate comparison.
