Answer:
d. credit card a is the better deal over the course of the first 3 months, but credit card b is the better deal over the course of the first year.
Step-by-step explanation:

2. 1430.5 is your total, then multiply that by .5% for intrest fee. Intrest fee is $7.153
3. You take $1430.5 + $7.153
TOTAL. $1437.65
Hope this helped.
