Answer:
2730$
Step-by-step explanation:
The amount of money left in the account after n years is given by the equation
where
is the initial amount of money
r is the rate of interest
n is the number of years
In this problem, we have:
is the initial amount of money
is the interest rate (5%)
n = 1 is the number of years
Therefore, the amount of money after 1 year is
Answer:
x = 6.00 $/kg ----> almond
y = 3.5 $/kg ------> nut
Step-by-step explanation:
To find the price per kg of each product you first write the algebraic equations for the given relations:
x : price per kg of almond
y: price per kg of nut
Then, you have:
5x + 4y = 44.00 (1)
8x + 6y = 69.00 (2)
By using substitution you have from (1):
y = (44.00-5x)/(4) = 11.00 - (5/4)x
you replace this expression for y into (2):
8x+6[11.00-(5/4)x] = 69.00
8x+66.00-(15/2)x = 69.00
8x-(15/2)x = 69.00 - 66.00
(1/2)x = 3.00
x = 6.00 $/kg ----> almond
And for nut:
y = 11.00 - (5/4)x = 11.00 - (5/4)(6.00) = 3.5$/kg
y = 3.5 $/kg ------> nut

Answer:
y=0
Step-by-step explanation:
-2(4+3y)=-2(4+y)
-8-6y=-8-2y
+8 +8
-6y=-2y
+2y +2y
-4y=0
-4y/-4=0/-4
y=0
