5.00 is the answer! It is very close to 5 therefore it would immediately go to 5!

1) Let's evaluate that expression, given that a=4.9, b=-7, and c=-0.5

Note that we have rewritten it as a fraction so that we can easily operate. Also, we have applied here the PEMDAS order of operations, prioritizing the exponents.

Answer:
2400 and 3600
Step-by-step explanation:
Radio 1 cost = x
Radio 2 cost= 6000- x
- x*1.2+(6000-x)*0.9= 6000*1.02
- 1.2x-0.9x+5400=6120
- 0.3x= 6120-5400
- 0.3x= 720
- x=720/0.3
- x= 2400
- 6000- x= 3600
