Answer:
270
Step-by-step explanation:
Area = length × width
Is it just x=b-cd
If so
cd=b-x
÷d. ÷d
C=b-x/d
The scale factor is 5/3
9(5/3) = 15
Part A
Your problem statement already shows you the conversion.
Bottles purchased: 5×10¹⁰
Bottles recycled: 8.3×10⁹
Part B
The ratio of bottles purchased to bottles recycled is
... (5×10¹⁰)/(8.3×10⁹) = 0.6×10¹ = 6.0
The number of bottles purchased is 6 times the number of bottles recycle.
