Fanny spent
37 of her money on 6 foolscaps and 3 highlighters. The cost of one highlighter was four times the cost of one foolscap. She bought some more highlighters with
13 of her remaining money. How many highlighters did Fanny buy altogether?

Cost of 1 foolscap = 1 u
Cost of 1 highlighter = 4 u
Cost of 6 foolscaps = 6 x 1 u = 6 u
Cost of 3 highlighters = 3 x 4 u = 12 u
Total cost of 6 foolscaps and 3 highlighters
= 6 u + 12 u
= 18 u
9 p = 18 u
1 p = 18 ÷ 9 = 2 u
Amount that Fanny used to buy more highlighters
= 4 p
= 4 x 2 u
= 8 u
Number of more highlighters that Fanny bought
= 8 u ÷ 4 u
= 2
Total number of highlighters that Fanny bought
= 3 + 2
= 5
Answer(s): 5
