To find out how many dollars you would receive for 22 Dinars, we can first establish the exchange rate:
The exchange rate is $4 for 2 Dinars.
We can find how many dollars 1 Dinar is worth by dividing the dollar amount by the Dinar amount:
\[ \text{Dollar per Dinar} = \frac{4 \text{ dollars}}{2 \text{ Dinars}} = 2 \text{ dollars per Dinar} \]
Now, to find out how many dollars you would receive for 22 Dinars:
\[ \text{Dollars received} = 22 \text{ Dinars} \times 2 \text{ dollars per Dinar} = 44 \text{ dollars} \]
Thus, if you exchanged 22 Dinars, you would receive 44 dollars.
