Step-by-step explanation:

A population can be defined as the total number of living organisms living together in a particular place and sharing certain characteristics in common.

The owner of a new restaurant wants to have seating for more than 75 people. There is currently a
Fudgin [204]

Answer:

4m+3>75

Step-by-step explanation:

Given:

Number of people to be seated should be greater than 75.

Let n be the number of people. So,

n > 75

Now, there is a single private chef's table that can seat 3 people.

Tables bought by the owner = m

Number of people seated in 1 table = 4

So, number of persons that can be seated in m tables = 4\times m=4m

Now, total number of persons that can be seated in these two types of tables is the sum of 3 and 4m

Therefore, n = 4m+3

But, n>75

Hence, the inequality to show the situation is:

4m+3>75
