the answer is 130.66

We know that 1 USD equals 1.31 CAD. If Mitchell exchanges 150 USD, how much CAD would be?

Then, he spends 20 CAD, so he return to the US with 176.50 CAD. How much USD would he have?

Therefore, Mitchell would have 134.70 USD.

Going by current exchange rates, Mitchell has $134.13 dollars remaining.

The current exchange rate of Canadian dollars to US dollars is:

CAD $ 1.26 : 1 USD

When Mitchell first exchanged the USD to CAD$, it became:

= 150 x 1.26

= CAD$ 189

He then spends CAD$ 20 which leaves him with:

= 189 - 20

= CAD$ 169

He then exchanges this back to US$:

= 169 / 1.26

= US$ 134.13

Mitchell has US$ 134.13 remaining.
