Answer:
Number of stamp Amanda has = 112
Step-by-step explanation:
Given:
Total number of stamp = 364
Number of stamp Lyle has = x
Number of stamp Shaquille has = [1/2]x
Number of stamp Amanda has = [2/3]x
Find:
Number of stamp Amanda has
Computation:
Total number of stamp = Number of stamp Lyle has + Number of stamp Shaquille has + Number of stamp Amanda has
Total number of stamp = x + [1/2]x + [2/3]x
364 = 13x / 6
x = 168
So,
Number of stamp Amanda has = [2/3]168
Number of stamp Amanda has = 112
