Carlos was planning a trip to saudi arabia. before going, he did some research and learned that the exchange rate is 3.7 riyals for $1. how many riyals would he get if he exchanged $3.80?

14.06 Riyals

Step-by-step explanation:

Given:

The exchange rate 3.7 Riyals for $1.

And Carlos exchanged $3.80.

We need to find how many Riyals would he get if he exchanged $3.80.

The exchange rate of $1 = 1 3.7 = 3.7 Riyals

For $2 = 2 3.7 = 7.4 Riyals

Similarly for $3.80 = 3.80 3.7 = 14.06 Riyals

Therefore, the exchange rate of $3.80 is 14.06 Riyals.

assuming you mean addition: addition and subtraction are reverse operations.
