Anthony borrows $6.50 from a friend to pay for a sandwich and drink at lunch. Then he borrows $3.75 from his sister to pay a library fine.
Choose an equation to express Anthony's total debt that day.
$6.50 + (–$3.75) = $2.75
–$6.50 + $3.75 = –$2.75
–$6.50 + (–$3.75) = –$10.25
$6.50 + $3.75 = $10.25
