Answer:
A. -10.21
Step-by-step explanation:
We know that he bought 3 sets of pencils for $30.63, so assuming each set costs the same amount, we divide 30.63 (the total cost) by 3 (the number of sets purchased) which would give us 10.21. Because we know that this money would have been subtracted from his bank account, then we know that it is a negative number.
Meaning the final answer would be -10.21
