Show the model answer
Totals: 1984 = 205; 1985 = 240; 1986 = 250; 1987 = 425; 1988 = 380 (₦m)
Draw one bar per year on the horizontal axis; vertical axis in ₦m with a suitable scale (e.g. 2 cm to ₦50m) up to at least 425.
Each bar's height = the year's total, divided into three components stacked in the same order every year: savings at the bottom, current next, fixed deposit on top (e.g. 1984: 0–100 savings, 100–165 current, 165–205 fixed deposit).
Shade/colour each component differently and give a key, title, axis labels and scale.
Same component order and shading in every bar.
