Answer:
$671.13
Step-by-step explanation:
Abby had a checkbook balance of $1,002.45
$76.98 was paid to the electric company
$254.34 was paid to the water company
Therefore the current checkbook balance can be calculated as follows
=$1,002.45-($76.98+$254.34)
= $1,002.45-$331.32
= $671.13
Hence Abby's current checkbook balance is $671.13
