Hope this helped. Would you like me to explain how I got it?
15% as decimal is 0.15 so 90g*0.15= 13.5
so the equation is 90g*15%=13.5
Solution:
Let number of upgrade options = p
Let total number of distinct variations in which 256 new homes is available = k
So, p × p× p.....k times = 256
⇒
256= 2 × 2 ×2 ×2 ×2 ×2 ×2 ×2= 
256= 4 ×4 ×4 × 4=
So,Either, number of upgrade options = 2 ,
Or , Number of upgrade options = 4
Answer:
18
Step-by-step explanation:
