Hey there!
Step By Step:
Well so we know that 12 is about half of an 25. So what we are gonna do is to buy 3 of 12$ and 2 of 25$. 
3x12=36 and 2x25=50.
With adding those two last numbers, you’ll get $86.
Graph would be down below. 
Hope it helps :D

Answer:
- 85°
- 60°
Step-by-step explanation:
1. Angle JKL is half the measure of the intercepted arc JK.
   (1/2)JK = 1/2(360° -190°) = (1/2)(170°) = 85°
   angle JKL is 85°
__
2. The angle between tangents is the supplement of the intercepted arc.
   angle JKL = 180° -(360° -240°)
   angle JKL = 60°

Answer:
Step-by-step explanation:
So if 16 watches is 16000 rs, then if you want to make 3200 more rs, your total from 16 watches should be 19200 (which is 16000+3200)
so the rate per watch should be 19200/16 = 1200
So it should be 1200rs/watch is the rate
