This kind of problem appears in Chapter 1 or 2 of Think Mathematics 3A (often titled "Linear Equations in Two Variables" or "Graphs"). It teaches that real life isn’t always a direct proportion — a key insight. It teaches that real life isn’t always a

From ( h + 5r = 21 ) and ( h + 11r = 27 ), subtract to get ( 6r = 6 \Rightarrow r = 1 \text{ cm} ), then ( h = 16 \text{ cm} ). For 20 cups: ( 16 + 19\times 1 = 35 \text{ cm} ).

: The "3A" journey moves into drawing models—specifically Bar Models —to visualize word problems involving addition, subtraction, and the introduction of multiplication and division.
