Answer:
52
Step-by-step explanation:
40% of 130 is 52
There are 3 seats currently, and there will be 4m extra seats if he buys m tables.
So, buying m tables give a total of
seats.
If we want this total to be at least 75, we have

72 = 2 * 2* 2 * 3 * 3
120 = 2 * 2 * 2 * 3 * 5
The greatest common factor (GCF) would be gotten from the factors common to both 72 and 120.
The common = 2 * 2 * 2 = 8
The GCF = 8
