Answer:
on the third number it says 344,636 and there is a double 4
A=P(1+r/n)^nt- Compound formula
P = $200
r = 4% = 0.04
n = 12 -Amount of months in a year
t = 3 years
A = 200(1 + 0.04/12)^12 × 3
A = 200(1 + 0.0033)^36
A = 200(1.0033)^36
A = $225
What I understand from the following info is that you are traveling 40.4 km/hr and travel for 7.5 hours. 40.4 times 7.5= 303km. Hope i help.
16 + 4x = 24
16 + 4x - 16 = 24 - 16
4x = 8
x = 2
8x = 16
