If the price is p and the quantity of bread sold is q = 400 - 100p, the average collection, in reais, depending on the price p, is given by R (p) = (400 - 100p). P
For this collection to be R $ 300.00, you must have:
(400 - 100p). p = 300 ⇔ 4p - p² = 3 ⇔ p² - 4p + 3 = 0 ⇔ p = 1 or p = 3
R $ 300.00
The current price is R $ 3.00, as R $ 300,000 / 100 = R $ 3
To maintain the collection, the price must be lowered to R $ 1.00 (R $ 0.50 <R $ 1.00 <R $ 1.50)
ANSWER: letter A
This is true.
a = 2b
Subtract both sides by c
a - c = 2b - c
Have an awesome day! :)

Answer:
Step-by-step explanation:
z = 2(cos7π/6 +isin7π/6)
cos7π/6 = cos(π/6+π) = - cos(π/6) = - √3 /2
sin7π/6 = sin(π/6+π) = - sin(π/6) = - 1 /2
so : z = 2( - √3 /2+i(- 1 /2))
z= - √3 - i .....(standard form)
