Answer:
C. $3
Explanation:
10% of $23.47 is 2.347. Just move the decimal over to the left one place and round up to get the closes dollar amount. Since the 4 is followed by a 7, which is greater than 5, the closest dollar amount would be $2.35. $2.35 is closer to $3 than it is to $1 so to tip the closest to 10%, you would tip $3.
