Answer:
$19.8
Step-by-step explanation:
To find the answer, find the ratio.
The profit is 10,000 dollars if the profit she sells is 60 kilograms
Given
The average daily balance is $15
The daily periodic rate = 0.06%
The number of days in the cycle is 30
Find out the monthly finance charge.
To proof
Let us assume that the monthly finance charge = x
As given in the question
The average daily balance = $15
daily periodic rate = 0.06%,
First convert 0.06% in decimal form

= 0.0006
Daily finance charge = 0.0006 × 15
= 0.009
number of days in the cycle is 30
now
monthly finance charge
Than the equation becomes
x = 15 × 0.0006 × 30
x = 0.009× 30
x = $0.27
Thus the monthly finance charge is $0.27
Hence proved
1) 2/5
2) 3/7
3) - 7/18
4) 3/5
5) - 5/18
6) 8/21
7) 2/5
8) -5
9) 9
10) 4 1/2
11) - 77/20
12) 6 10/21
