Answer:
150
Step-by-step explanation:
you have three days and 7.5 so decide 7.5 by 3 it equals 2.5 which in minutes is 150
Its $800 because to find interest u can use the formula I=PRT p is principal which is 500 times r which is rate-15/100(=15%) times 4
so the interest is 500×15/100×4=300
then u add 300 to 500 because the interest adds more money to the loan
