Answer:
The interest rate per year is 0.1
Step-by-step explanation:
The equation is A = P(1+rt)
Substitute the numbers
3500 = 2500 (1+4r)
solve for r:
2^9 = 2 x 2 x2 x 2 x 2 x 2 x2 x 2 x 2 = 512
2 ^9 = 512
K = (y °F – 32) ÷ 1.8 + 273.15 or K = (y °F – 32) x 5/9 + 273.15
wait, I will look my lecture last year
