There are 14 tables with 8 chairs and 26 tables with 6 chairs in the cafe.
Step-by-step explanation:
Given,
Total tables at the cafeteria = 40
Table with 8 chairs = 35% =
Tables with 6 chairs = 65% =
Number of tables with 8 chairs = 0.35*Total tables
Number of tables with 8 chairs = 0.35*40 = 14 tables
Number of tables with 6 chairs = 0.65*40 = 26 tables
Therefore,
There are 14 tables with 8 chairs and 26 tables with 6 chairs in the cafe.

Here is my answer. Let just give assumptions. For example,the relationship is linear.Therefore the slope, "m," is the same throughout.
Let us make patrons the independent variable, the two points are: (1314, 11333) and (1544, 13518).
m = (13518-11333)/(1544-1314)
m = 9.5
profit = 9.5 patrons (you pick the variable names)
For 1 more patron substitute 1:
profit = 9.5 (1)
profit = 9.5
Isolate "patrons" and you get the function based on profit:
patrons = profit/9.5
The break even point is for 0 < profit.
0 < profit = 9.5 patrons
0 < 9.5 patrons
0 < patron
Greatest common factor (GCF) of 12 and 21 is 3. We will now calculate the prime factors of 12 and 21, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 12 and 21.
First add 2 to both sides to cancel:
x/3 = 5
then multiply by 3 to both sides to cancel the 3:
x=15
