Answer:
(-2, -1), and (1, 2)
Step-by-step explanation:
i made a grid and i made a square with the -2, 2 and 1, -1.
Add an + in between 5x5 and 5x2
Let x represent the number of type A table and y represent the number of type B tables.
Minimize: C = 265x + 100y
Subject to: x + y ≤ 40
25x + 13y ≥ 760
x ≥ 1, y ≥ 1
From, the graph the corner points are (20, 20), (39, 1), (30, 1)
For (20, 20): C = 265(20) + 100(20) = $7,300
For (39, 1): C = 265(39) + 100 = $10,435
For (30, 1): C = 265(30) + 100 = $8,050
Therefore, for minimum cost, 20 of type A and 20 of type B should be ordered.

Answer:
Cost of a single light bulb is $3.34
Step-by-step explanation:
Value of sales tax = 6% ×$71.02
= $4.2612
Total cost of bulb before tax = Total cost of bulb - Value of sales tax
= $71.02 - $4.2612
= $66.7588
Value of a single light bulb = Total cost of bulb before tax ÷ Total number of light bulbs
= $66.7588 ÷ $20
= $3.33794
= $3.34 Approximately.
