The percentage increase from Day 2 to Day 3 of the birds is =20%
<h3>Calculation of Percentage Increase</h3>
Day One = 16 birds
Day two = 16 - 25% (16)
But 25% (16) = 25/100 ×16
= 1/4× 16
= 4
Therefore day two = 16 - 4 = 12
Day three = 12 + 3 = 15
Therefore percentage increase,
= 3/15 × 100
= 300/15
= 20%
Therefore there was 20% increase from Day 2 to Day 3.

Answer:
Step-by-step explanation:
The function is f(x) = -4x²+10x-8
Let Δ be our the dicriminant
- Δ= b²-4ac
- b = 10
- a = -4
- c = -8
- Δ = 10²-4*(-4)(-8)
- Δ = 100-128
- Δ = -28
The value of the discriminant is -28 and since it is negative this function has no real zeroes
The original price of the item will be $ 480.When there is 75% off on the original price.
<h3>What is the percentage?</h3>
The quantity of anything is stated as though it were a fraction of a hundred. A fraction of 100 can be used to express the ratio.
The right question is
"Joyce saved $120 on an item that was 75 % off. What was the original price?"
Given data;
% off = 75
Amount saved $120
Let the original price of the item is x
75 % of x + $120 = x
0.75x+ 120 =x
0.25 x =120
x=120/0.25
x=480
Hence, the original price of the item will be $ 480.
