Final answer:
Evelyn can make 4 identical bracelets using 16 pink beads and 32 purple beads. Hence the correct answer is option A
Step-by-step explanation:
Evelyn has a total of 16 + 32 = 48 beads. Since the number of pink beads is half the number of purple beads, she has 32 / 2 = 16 pink beads. This means she can make 16 identical bracelets, each with 16 pink beads and 32 purple beads. Therefore, the correct answer is (a) 4.
