Answer:
Option A: 3x + 5x - 4 = 1
Step-by-step explanation:
Given that:
3x + y = 1 ------------- eq1
y + 4 = 5x ------------ eq2
Now for substitution in eq1 we will get a value of y from eq2:
y = 5x - 4
Substituting in eq1 we get:
3x + 5x - 4 = 1

Given that Sally's balance on her credit card is $75.00 on the first day of August, and she makes a payment of $18.00 on August 17 and a new purchase of $41.00 on August 29, and the annual interest rate is 21.25%, to determine what is Sally's average daily balance and finance charge for the month of August, the following calculation must be made:
- 75 x ((21.15/12 x 16) / 100) + 75 = A = 86.89
- 57 x ((21.15/12 x 13) / 100) + 57 = B = 70.06
- 98 x ((21.15/12 x 3) / 100) + 98 = C = 103.18
- (86.89 x 16 + 70.06 x 13 + 103.18 x 3) / 31 = X
- 84.21 = X
- 86.89 + 70.06 + 103.18 - 75 - 57 - 98 = Y
- 30.13 = Y
Therefore, the average daily balance for the month was $84.21, and the finance charge for the month was $30.13.
