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

Case 1 :
Radius, r = 5 feet.
Area,
Case 2 :
Diameter, d = 56 mm.
So, radius, r = d/2 = 28 mm.
Area,
Hence, this is the required solution.
If we write this algebraically: 2x-7=-147
Add 7 to both sides: 2x=-140
Divide both sides by 2: x=-70
x=-70
