Using sin(A+B) = sinAcosB + cosAsinB
sin20cos40 + cos20sin40 = sin(20+40) = sin60degree

Answer:
- 2000: 17.60 per pound
- 2010: 163.91 per pound
- 2025: 4,658.68 per pound
Step-by-step explanation:
We assume your formula is intended to be ...
p(t) = 17.6(1.25^t)
__
For t=0, ...
p(0) = 17.6
For t=10, ...
p(10) = 17.6·1.25^10 ≈ 163.91
For t=25, ...
p(25) = 17.6·1.25^25 ≈ 4,658.68
Multiply both sides
8x-96=3x+24
move the terms
8x-3x=24+96
collect like terms
5x=120
solution:
x=24
