99 is more than 100 when you add 2 to 99. xD
If APR is 24.99%, this means that the monthly rate is 24.99/12 = 2.0825%. T0 - Time of Purchase - Principal amount is $396 T1 - 1 month after purchase - Amount owing is 396*1.020825 = $404.25 5% of that sum is $20.21 Remaining balance is 404.25-20.21 = $384.04 T2 - 2 months after purchase - Amount owing is 384.04*1.020825 = $392.04 5% of that sum is $19.60 Remaining balance after 2 months is 392.04-19.60 = $372.44 T3 - 3 months after purchase - Amount owing is 372.44*1.020825 = $380.20 5% of that sum is $19.01 Remaining balance after 3 months is 380.20 - 19.01 = $361.19. Seeing by your answer choices i would say Option D is your closest Hope it helps !!
Obviously if it takes him around 12 hours to drive 1158 km. Then by ratio method we can calculate how much time it takes for him for one hour. So 1158/12 = 96.5 in one hour.
Now for the next part we can see he drove around 484 after 5 hours. So we can see his average of 1 hour by 484/5 = 96.8 so according to this pace he might arrive a little before time.
