9. 1/2 or 0.5 (3x=42; what is 7/x?)

14. 56 (purchasing 24 things at \$35 with a 10% discount versus purchasing 25 things at a 20% discount)
15. 862 (largest 3-digit number whose digits multiply to 96)

17. 0 < x < 0.1 (x/x^2 is greater than 10; what could x be?)
18. 24 (minimum perimeter of an arrangement of 4×4, 3×3, 2×2, and 1×1 squares)
