Mitchell travels from the us to canada, where he exchanges 150 us dollars for canadian dollars. he then spends 20 canadian dollars, returns to the us, and exchanges the remaining money back to us dollars. how many us dollars does mitchell have remaining?

He has remaining 135 US Dollars. ( approx )

Step-by-step explanation:

Since, 1 US dollar = 1.32 Canadian dollars,

⇒ 150 US dollars = 150 × 1.32 = 198 Canadian dollars,

Thus, if he exchanges 150 US dollars for Canadian dollars,

Then, the canadian dollars he has initially = 198,

Now, after Spending 20 canadian dollars,

The remaining Canadian dollars he have after returining to US = 198 - 20 = 178,

Again, 1.32 canadian dollars = 1 US dollar

Hence, the remaining US dollars he have after returning to US is 135.
