The final cost in dollars to buy robotic kits for the Science Club can be found using the function c = 49.85n + 7.95, where n is the number of kits purchased. They want to purchase at least 8 kits but not more than 12 kits. What is the domain of the function for this situation?

Respuesta :

The given expression is

[tex]c=49.85n+7.95[/tex]

Where n is the number of kits purchased, and c is the final cost.

If the want to purchase at least 8 kits but no more than 12 kits then this means the number of kits is restricted from 8 to 12.

In other words, the domain for this situation is

[tex]D\colon8\leq n\leq12[/tex]

In words, the domain is all real numbers more than or equal to 8 and less than or equal to 12.
