Answer:
The 225 US dollars does he now have a (C) $125.
Step-by-step explanation:
After exchanging 250 US dollars for euros, Albert spent 150 euros. To determine how much of the 225 US dollars he has left, we need to convert the amount spent in euros back to US dollars. If Albert spent 150 euros, and the exchange rate is such that 1 euro equals 1 US dollar, then he spent 150 US dollars. Subtracting this from the original amount gives us 225 US dollars - 150 US dollars = 75 US dollars.
Therefore, Albert now has 75 US dollars. Adding this to the amount he initially spent, 150 US dollars, gives a total of 225 US dollars.
Option C is correct.
