Answer:
The number of stores in California 42
The number of stores in Nevada 18
Step-by-step explanation:
Given as :
The total sandwich shop in California and Nevada = 60
The percentage of shop in California = 70%
So, The percentage of shop in Nevada = 100% - 70% = 30%
Let The number of stores in California = c
And The number of stores in Nevada = n
Now, According to question
The number of stores in California = 70% of the total number of shops
I.e c = × total number of shops
Or, c = × 60
∴ c =
or, c =
or, c = 42
So, The number of stores in California = c =42
Again
The number of stores in Nevada = 30% of the total number of shops
I.e n = × total number of shops
Or, n = × 60
∴ n =
or, n =
or, n = 18
So, The number of stores in Nevada = n = 18
Hence The number of stores in California 42
And The number of stores in Nevada 18 Answer
