In a shop, the number of correction tapes was
23 of the total number of correction tapes and glues together. Elijah sold the correction tapes and glues in sets of 1 correction tape and 8 glues. After selling all the glues, he still had 45 correction tapes left. How many glues were in the shop at first?

Correction Tapes |
Glues |
| Before |
2x8 =
16 u |
1x8 =
8 u |
| Change |
- 1x1 =
- 1 u |
- 8x1 =
- 8 u |
| After |
45 |

Since all the glues were sold, the number of glues at first and the number of glues sold were the same. Make the number of glues at first and sold the same. LCM of 1 and 8 is 8.
Number of correction tapes sold
= 16 u - 1 u
= 15 u
15 u = 45
1 u = 45 ÷ 15 = 3
Number of glues at first
= 8 u
= 8 x 3
= 24
Answer(s): 24
