The number of stores in California 42
The number of stores in Nevada 18
Step-by-step explanation:

The total sandwich shop in California and Nevada = 60
The percentage of shop in California = 70%

The number of stores in Nevada = 30% of the total number of shops
I.e n = × total number of shops
Or, n = × 60
