Answer:
b = 20x beads
Step-by-step explanation:
In this question, we will be trying to relate the number of beads to the number of bracelets.
From the question, we can identify that each of the bracelets will have 20 beads. The total number of bracelets to be made is x. This means that the total number of beads to be used can be calculated by multiplying 20 by x = 20x beads. This number is same as b, which is equal to the total number of beads.
Hence, we can say that b = 20x beads
