No. 10 board books at $1.50 = $15.00 and 5 soft-cover at $0.50 = $2.50, total = $17.50, not $20.
He would need $2.50 more to reach $20. Since boards cost $1.50 and soft-covers $0.50, the extra $2.50 can be made by:
- adding 5 more soft-covers (0 board, 5 soft) → 10 board + 10 soft = $20, or
- adding 1 more board and 2 more soft-covers (1.5 + 1.0 = 2.5) → 11 board + 7 soft = $20.
