Linda spent
25 of her money on 2 pens and 7 correction tapes. The cost of one correction tape was twice the cost of one pen. She bought some more correction tapes with
16 of her remaining money. How many correction tapes did Linda buy altogether?

1x1 |
5x1 |
| 4 p |
1 p |
5 p |
Cost of 1 pen = 1 u
Cost of 1 correction tape = 2 u
Cost of 2 pens = 2 x 1 u = 2 u
Cost of 7 correction tapes = 7 x 2 u = 14 u
Total cost of 2 pens and 7 correction tapes
= 2 u + 14 u
= 16 u
4 p = 16 u
1 p = 16 ÷ 4 = 4 u
Amount that Linda used to buy more correction tapes
= 1 p
= 1 x 4 u
= 4 u
Number of more correction tapes that Linda bought
= 4 u ÷ 2 u
= 2
Total number of correction tapes that Linda bought
= 7 + 2
= 9
Answer(s): 9
