To find: how linear equation and inequalities are similar and different.

Answer to Problem 37E
The linear equation uses a solid line and linear inequality used a dashed line.
Explanation of Solution
Given:
Linear equation and linear inequalities.
Concept used:
Linear equation has one solution whereas linear inequality has many solutions.
Linear equation forma line as solution and linear inequality solution is represented by the area.
Calculation:
The following points represent some of the similarities and differences:
It looks all very similar and the algebraic manipulations remain the same while plotting the line but in inequality, it need to consider if the boundary line is dashed or solid depending on the inequality symbol used.
Ina linear equation, switching the sides do not affected on the equal sign but in linear inequality, switching sides brings in an Automatics change in signs, that is from greater than to less than and vice versa.
This is also happened when both sides of inequality are multiplies or divided by a negative number.
The solution of the linear equation gives an ordered pair while the solution of the linear inequality gives a region, either above or below the curve line.
Hence, linear equation uses a solid line and linear inequality used a dashed line.

The clubs will sell for $895 per set and have a variable cost of $431 per set. The company has spent $200,000 for a marketing study that determined the company will sell 80,000 sets per year for seven years. The marketing study also determined that the company will lose sales of 8,600 sets per year of its high-priced clubs. The high-priced clubs sell at $1,325 and have variable costs of $645. The company will also increase sales of its cheap clubs by 10,800 sets per year. The cheap clubs sell for $340 and have variable costs of $141 per set. The fixed costs each year will be $14,350,000. The company has also spent $1,500,000 on research and development for the new clubs. The plant and equipment required will cost $43,700,000 and will be depreciated on a straight-line basis. The new clubs will also require an increase in net working capital of $3,625,000 that will be returned at the end of the project.
