Answer:
Step-by-step explanation:
Let, Marat can buy x specialty doughnuts and y glazed doughnuts.
Marat will be able to buy the doughnuts if [tex]2x + y \leq 16[/tex].
If we put x = 0 in 2x + y = 16, then y = 16.
For y = 0, x = 8.
Marat can buy 0 doughnuts or can buy some, but the total amount needs to be in between 16.
