Emma spent
38 of her money on 4 glues and 8 correction tapes. The cost of one correction tape was four times the cost of one glue. She bought some more correction tapes with
13 of her remaining money. How many correction tapes did Emma buy altogether?

1x5 |

| 9 p |
5 p |
10 p |
Cost of 1 glue = 1 u
Cost of 1 correction tape = 4 u
Cost of 4 glues = 4 x 1 u = 4 u
Cost of 8 correction tapes = 8 x 4 u = 32 u
Total cost of 4 glues and 8 correction tapes
= 4 u + 32 u
= 36 u
9 p = 36 u
1 p = 36 ÷ 9 = 4 u
Amount that Emma used to buy more correction tapes
= 5 p
= 5 x 4 u
= 20 u
Number of more correction tapes that Emma bought
= 20 u ÷ 4 u
= 5
Total number of correction tapes that Emma bought
= 8 + 5
= 13
Answer(s): 13
