Answer:
100% of the pizzas have 12 slices or 8 slices
(20x.45x8) + (20x.55x12) = total slices
4 + 3 = 7, 7 + 7 = 14, 7 + 0 = 7, 7 + 7 = 14. 14 = 14 Fourteen is equal to fourteen so the answer is =

Answer: 12,503 people
Step-by-step explanation:
This is an exponential decrease so to find the population in 8 years you have to use a future value formula:
= Amount * (1 + rate) ^ number of years
= 15,000 ( 1 + (-2.25%)) ⁸
= 15,000 * (1 - 2.25%)⁸
= 12,503.32
= 12,503 people
