Olivia spent ⁵₈ of her money on 8 post-it pads and 6 correction tapes. The cost of one correction tape was twice the cost of one post-it pad. She bought some more correction tapes with ¹₆ of her remaining money. How many correction tapes did Olivia buy altogether?

8 post-it pads and 6 correction tapes	Remaining amount
5x2	3x2
	More correction tapes	Left
	1x1	5x1
10 p	1 p	5 p

Cost of 1 post-it pad = 1 u
Cost of 1 correction tape = 2 u

Cost of 8 post-it pads = 8 x 1 u = 8 u
Cost of 6 correction tapes = 6 x 2 u = 12 u

Total cost of 8 post-it pads and 6 correction tapes
= 8 u + 12 u
= 20 u

10 p = 20 u

1 p = 20 ÷ 10 = 2 u

Amount that Olivia used to buy more correction tapes
= 1 p
= 1 x 2 u
= 2 u

Number of more correction tapes that Olivia bought
= 2 u ÷ 2 u
= 1

Total number of correction tapes that Olivia bought
= 6 + 1
= 7

Answer(s): 7
