Answer:
11/16 of a pound of confetti is left for the next Annual celebration
Step-by-step explanation:
Confetti made by the Ortega family = 15/16 of a pound for the Annual celebration
Confetti used = 1/4 of a pound
Confetti left for the next year = 15/16 - 1/4
Confetti left for the next year = 15/16 - 4/16 = 11/16
11/16 of a pound of confetti is left for the next Annual celebration
