The equation in H form is :-
h = πr2/v
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
Let x represent milk chocolate bar
y represent creamy nougat bars
3x+4y=4.25
6x+4y=6.5
6x+4y=6.5
-
3x+4y=4.25
=
3x=2.25
x=$0.75
y=$0.5. As a result, one milk chocolate bar costs $0.75 and one creamy nougat bar costs $0.5. Hope it help!
The answer to the question is 48 and 49
Answer:
22 years
Step-by-step explanation:
Well we know the formula for simple interest is
I = PRT
I = interest earned
P = initial balance
R = rate
T = time
We want to solve for time here....so rearrange for T
T= I/(PR
)
We have
P = 825
R = .057
And I = current balance - initial balance = 1859.55 - 825 = 1034.55
So plugging all those in we have
T = 1034.55/(825×.057
)
T = 1034.55/47.025
T = 22
