Step-by-step explanation:
Answer:
1) (D)
2) (B)
3) (C)
Step-by-step explanation:
1) Amount borrowed = $1380 (P)
APR =13% or 0.13 (R)
Time = 15 months (T) = 15/12
Interest amount = 
= 
= $224.25
Total amount = 1380+224.25
= $1604.25

2) Amount borrowed = $2240
APR = 15% or 0.15
Time = 18 months
Interest =
= 
= $504 (B)
3) Amount borrowed = $5500
APR = 11.5% or 0.115
Time = 5 years
n= 12 (compounded monthly)
M = 
= 
= $120.95 (C)
