Model Drawing illustration for the earlier working:

For Valerie's number of beads to be the same as Jess', we need to multiply her number 3 times.

So, 3 times of 6 units is 18 units and then it will be as long as Jess' (8 units + 120).

From the model drawing, we can see that 10 units = 120.

Hope this is clear now.
