Answer:
The inflation rate of increase is 9.22 %
Step-by-step explanation:
Given as :
The initial cost of gas = i = $1.46
The final cost of gas after 10 years = f = $3.53
The time period for increase = n = 10 years
Let The inflation rate of increase = r %
<u>Now, According to question</u>
Inflation rate = [ - 1 ] × 100
Or, r = [ - 1 ] × 100
Or, r = [ - 1 ] × 100
Or, r = - 1 ] × 100
Or, r = [ 1.0922 - 1 ] × 100
∴ r = 0.0922 × 100
i.e r = 9.22 %
So,The inflation rate of increase = r = 9.22 %
Hence, The inflation rate of increase is 9.22 % Answer
