310 as many beads as Diana. After Luis bought another 44 beads, he had 12 less beads than Diana. How many beads did Luis have at first?

Before |
3 u |
10 u |

+ 44 |

After |
3 u + 44 |
10 u |
Diana had 12 more beads than Luis in the end. So, if Luis had another 12 beads, he would have the same number of beads as Diana.
10 u = 3 u + 44 + 12
10 u - 3 u = 44 + 12
7 u = 56
1 u = 56 ÷ 7 = 8
Number of beads that Luis had at first
= 3 u
= 3 x 8
= 24
Answer: 24
