Kimberly had five times the number of toy blocks as Oliver. Kimberly used all her blocks to build 11 identical figurines. Oliver used all his blocks to build 4 identical figurines. Kimberly used 9 more blocks than Oliver for each figurine. How many blocks did Oliver have?

Kimberly |
Oliver |
| Number |
11 |
4 |
| Value |
1 u + 9 |
1 u |
| Total value |
11 u + 99 |
4 u |
Number of toy blocks that Oliver used for each figurine = 1 u
Number of toy blocks that Kimberly used for each figurine = 1 u + 9
Number of toy blocks that Oliver had
= 4 x 1 u
= 4 u
Number of toy blocks that Kimberly had
= 11 x (1 u + 9)
= 11 u + 99
Kimberly had five times the number of toy blocks as Oliver.
5 x 4 u = 11 u + 99
20 u = 11 u + 99
20 u - 11 u = 99
9 u = 99
1 u = 99 ÷ 9 = 11
Number of blocks that Oliver had
= 4 u
= 4 x 11
= 44
Answer(s): 44
