Since she already returned half of the money, then this means she currently owes her brother $60. Four months from now, she will be able to pay an additional $10 x 4 = $40. Thus, she will still owe her brother $60 - $40 = $20 four months from now.
The question and answer pair are described below. <ibo> N'ime ọnwa isii, Shara nwere ike inyeghachi nwanne ya nwoke $10 x 6 = $60.
