Answer 1

Lauren used 16 beads to make the bracelet and 4 beads were not yellow.

Step-by-step explanation:

Lauren used the rule "Purple, Yellow, Yellow, Purple" to make a bracelet with a repeating pattern. She used 12 yellow beads. To find out how many beads Lauren used to make the bracelet, we need to add up the number of purple beads, the number of yellow beads, and the number of purple beads. According to the rule, there are 2 yellow beads in each repeating pattern, so Lauren used a total of 2 + 12 + 2 = 16 beads to make the bracelet.

To find out how many beads were NOT yellow, we need to subtract the number of yellow beads from the total number of beads. The total number of beads is the same as the number of purple beads since each purple bead is part of a repeating pattern. Therefore, the number of beads that were NOT yellow is 16 - 12 = 4 beads.
