100t would be what you would use and once you know how many hours or need to find the number of cells you substitute
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 !!
Answer:
A)336
B) In how many ways can you arrange 8 people in 3 different chairs?
C) 21
D) You want to buy 3 cartoon books from a book store that has 7 cartoon books. In how many ways can you select?
Step-by-step explanation:
A) P(n, r) = P(8, 3)
Formula for permutation is;
P(n, r) = n!/(n - r)!
P(8, 3) = 8!/(8 - 3)!
P(8, 3) = (8 × 7 × 6 × 5!)/5!
5! will cancel out to give;
P(8, 3) = (8 × 7 × 6)
P(8, 3) = 336
B) In how many ways can you arrange 8 people in 3 different chairs?
C) C(n, r) = C(7, 2)
Formula for combination is;
C(7, 2) = n!/(n - r)!r!
Thus;
C(7, 2) = 7!/(7 - 2)!2!
C(7, 2) = (7 × 6 × 5!)/(5! × 2 × 1)
5! will cancel out to give;
C(7, 2) = 7 × 6/2
C(7, 2) = 21
D) You want to buy 3 cartoon books from a book store that has 7 cartoon books. In how many ways can you select?
