Answer:
Step-by-step explanation:
Given as :
For company A
The rate of charge = $40 per day
For company B
The rate of charge = $20 per day
The fixed charge = $60
Let The number of days for which the cost would be same = n days
Now, According to question
For cost to be same for both companies
The charge of company A = The charge of company B
So, charge per day × number of days = charge per day × number of days + fixed
Or, $40 × n = $20 × n + $60
Or, $40 × n - $20 × n = $60
Or, ($40 - $20) × n = $60
Or, $20 × n = $60
∴ n = [tex]\dfrac{60}{20}[/tex]
i.e n = 3
So, The number of days for which the cost would be same = n = 3 days
Hence,The number of days for which the cost would be same is 3 days . Answer
