Kimberly had five times the number of metallic blocks as Perry. Kimberly used all her blocks to build 12 identical figurines. Perry used all his blocks to build 3 identical figurines. Kimberly used 9 more blocks than Perry for each figurine. How many blocks did Perry have?

Perry |
| Number |
12 |
3 |
| Value |
1 u + 9 |
1 u |
| Total value |
12 u + 108 |
3 u |
Number of metallic blocks that Perry used for each figurine = 1 u
Number of metallic blocks that Kimberly used for each figurine = 1 u + 9
Number of metallic blocks that Perry had
= 3 x 1 u
= 3 u
Number of metallic blocks that Kimberly had
= 12 x (1 u + 9)
= 12 u + 108
Kimberly had five times the number of metallic blocks as Perry.
5 x 3 u = 12 u + 108
15 u = 12 u + 108
15 u - 12 u = 108
3 u = 108
1 u = 108 ÷ 3 = 36
Number of blocks that Perry had
= 3 u
= 3 x 36
= 108
Answer(s): 108
