Beatrice arranged some beads in 15 short rows and 14 long rows. there were 36 more beads in each long row than each short row. Beatrice used 70% of the beads she had to arrange the beads in long rows while the rest of the beads were arranged in short rows. How many beads were there in each short row?

steps and explanations pls

15 Short rows = 15 * X number of beads (15x)
15x = 30% of total beads
divide both by 15 (highest common denominator)
x = 2% of total beads

29x + (36 * 14) = 100% of beads
29x = 58% of total beads
36*14 = 504 = 42% of total beads
504/42 = 12 = 1% of total beads

12 * 58 = 696 = 29x
696 / 29 = x = 24

24 beads per short row
