Hilda spent ³₅ of her money on 2 highlighters and 8 correction tapes. The cost of one correction tape was twice the cost of one highlighter. She bought some more correction tapes with ¹₃ of her remaining money. How many correction tapes did Hilda buy altogether?

2 highlighters and 8 correction tapes	Remaining amount
3x3	2x3
	More correction tapes	Left
	1x2	2x2
9 p	2 p	4 p

Cost of 1 highlighter = 1 u
Cost of 1 correction tape = 2 u

Cost of 2 highlighters = 2 x 1 u = 2 u
Cost of 8 correction tapes = 8 x 2 u = 16 u

Total cost of 2 highlighters and 8 correction tapes
= 2 u + 16 u
= 18 u

9 p = 18 u

1 p = 18 ÷ 9 = 2 u

Amount that Hilda used to buy more correction tapes
= 2 p
= 2 x 2 u
= 4 u

Number of more correction tapes that Hilda bought
= 4 u ÷ 2 u
= 2

Total number of correction tapes that Hilda bought
= 8 + 2
= 10

Answer(s): 10
