8% of their total bill = 3.70
0.08x = 3.70
x = 3.70/0.08
x = 46.25 <==
Answer:
There's one important property which states that when a number is multiplied by its reciprocal, equals 1.
The commutative property of multiplication states that two or more numbers can be multiplied in any order, therefore, the expression: (7)×(13/29)×(1/7) can be changed to (7)×(1/7)×(13/29) and the result won't be altered.
Now, given that 7 and 1/7 are reciprocals, the result is 1. Therefore, the result of the multiplication equals (13/29)
Whole chicken unit price= $0.97
Chicken drumstick unit price= $1.02
Therefore the whole chicken is the better buy
Answer:
Step-by-step explanation:
xy = 2y + xy = 0
Hence, 2y + xy = 0 ---------(1)
Differentiating equation (1) n times by Leibnitz theorem, gives:
2y(n) + xy(n) + ny(n - 1) = 0
Let x = 0: 2y(n) + ny(n - 1) = 0
2y(n) = -ny(n - 1)
∴ y(n) = -ny(n - 1)/2 for n ≥ 1
For n = 1: y = 0
For n = 2: y(1) = -y
For n = 3: -3y(2)/2
For n = 4: -2y(3)
