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:

$4m+3>75$
