Answer to Problem 7CYU
The system of inequalities that represent the number of pro boards and specialty boardsis
Explanation of Solution
Given information:
A table that depicts time required to manufacture skateboards.
85 hours are available for production time and 40 hours are available for deck finishing and quality control.
Calculation:
Consider the provided information thata table that depicts time required to manufacture skateboards.
85 hours are available for production time and 40 hours are available for deck finishing and quality control.
Let x denote the number of pro boards manufactured and y denote the number of specialty boards manufactured.
1.5 hours for pro and 1 hour for specialty boards as production time each is required. Maximum 85 hours are available for production time is available.
Similarly, 2 hours for pro and 0.5 hours for specialty boards as deck finishing and quality control each is required. Maximum 40 hours are available for deck finishing and quality control.
The constraints are,
