Answer:
1) 2.71%
2) $38.32
Step-by-step explanation:
Opening balance = $1220
Balance after 10 days (after expense) = $1690
Balance after 10 days(after payment) = $1340
APR = 33%
1) Periodic interest rate = APR × 
= 33%× 30/365
= 2.71%
2) Interest charged for first 10 days = 
= $11.02
Interst charged for the next 10 days = 
= $15.2
Interest charged for the next 10 days = 
= $12.10
Total interest for 30 days = 11.02+15.2+12.10
= $38.32
Let the no of large frames bought be X
Then the no of smaller frames bought will be (17 - X )
Cost incurred = 14X + 5( 17 - X) = 130
14X + 85 - 5X = 130
9X = 45
X = 5
Answer 5 large frames and 12 small frames
Check
5X14 = 70
12X5 = 60
ADD = 130$
Answer:
The system has infinite solutions
Step-by-step explanation:
IF we re arrange the terms, we will find the following identity:
0=0
Meaning that any variable you find will not affect the equation 0=0,
60%
If you take the 30% and divide from the 50% you get .6 multiply that by a 100 you get 60.
30/50=.60
.60x100=60
60%
