Answer:
$4.00
Step-by-step explanation:
We assume the price is proportional to the quantity of oranges. If p is the desired price in dollars, we want ...
p/8 = 0.25/(1/2)
p = 8(0.50) = 4.00 . . . . multiply by 8, simplify
8 kg of oranges would cost $4.00.
A=p(1+i/m)^mn
P=3000
i=0.20
M=12
n=1/12
A=3,000×(1+0.20÷12)^(12*1/12)
=3,050
Interest earned=3050-3000=50
Set the equations equal to one another and solve for x
4x + 4 = -3x - 3
7x + 4 = -3
7x = -7
x = 1
Now pulg x into one of the equations:
y = 4(-1) + 4
y = -4 + 4 = 0
THe answer is now (-1, 0)
