To calculate the total amount of money Ari found, we add the value of the 1-dollar bills and the value of the dimes.
Ari has:
-
Four 1-dollar bills:
\(4 \times 1 = 4\) dollars. -
Three dimes:
Each dime is worth $0.10, so:
\(3 \times 0.10 = 0.30\) dollars.
Now, we add the amounts together: \[ 4.00 + 0.30 = 4.30. \]
So, the total amount of money Ari found is $4.30.
