I think the answer would be C but I am not certain.
Answer:
4 hours at 8 miles an hour: 8(4) = 32 miles in total
8 hours at 2 miles an hour: 2(8) = 16 miles in total
Miles in total: 32 + 16 = 48
The answer is A. 48 miles
12/100x10000 = 1200
17/100x8000= 1360
1360+1200 = 2560
18000 - 2560 = $15,440 (final cost)
F(m)=4m(3m-2)
f(m)=12(m^2)-8m
f(-3.3)=12(-3.3^2)-8(-3.3)
f(-3.3)=12(10.89)-(-26.4)
f(-3.3)=130.68+26.4
f(-3.3)=157.08
The annual discount is 3%, therefore the total discount for 1 year would be:
4300 × 3 ÷ 100 = 129$
Now, you can set a proportion:
discount : annual discount = loan days : days in one year
21 : 129 = x : 360
x = 21 × 360 / 129 = 58.6 days
Hence, the loan duration was 60 days.
