    1.2195

    Step-by-step explanation:

    For each month, he is given (on avg) $100 (CAD).

    If on avg he can spend $82 (USD) each month,

    then the USD: CAD ratio is

    100:82, meaning $1 (USD) is equivalent to $.82 (CAD)

    and the exchange rate is calculated by equating 1 =.82x

    thus, x = 1/.82 = 1.2195
