Answer:
D) credit card with an apr of 18 percent with a grace period of twenty-five days
Step-by-step explanation:
Finance is based on the premise that the value of money increases as time passes, so Sadie must look for the option that charges her the lowest APR and gives her some type of grace period or longer payment schedule.
Options B and C are the most expensive ones: B has the highest APR and C charges an application fee.
Option D is better than option A because it grants a grace period, a short one, since it's basically a month. A short grace period is better than no grace period.
