Answer: 10 inches per year.
If the snake is now 3 foot 9 inches, we can add up how many inches that is by converting feet to inches. 1 foot=12 inches, so 3 feet is 36 inches. We then add the 9 inches.
36+9= 45
Since the snake had already accomplished being 5 inches at birth, we can subtract 5 from 45.
This gives us 40.
Since the snake was born 4 years ago we divide 40 by 4.
40÷4= 10
Answer:
73.21% annual percentage rate.
Step-by-step explanation:
3 foot 9 inches = 45 inches
45 = 5(1 + r)4
9 = (1 + r)4
91/4 = 1 + r
r = 0.73205
therefore,
r = 73.21%
