The total cost of pizza and drinks, is an illustration of a linear function.
The model that represents the situation is: [tex]\mathbf{10 + 3d = 19}[/tex]
The given parameters are:
[tex]\mathbf{Total =19}[/tex]
[tex]\mathbf{1\ pizza =10}[/tex]
[tex]\mathbf{1\ drink =d}[/tex]
The cost of 3 drinks will be 3d
The total cost would then be:
[tex]\mathbf{Total = 10 + 3d}[/tex]
Substitute 19 for Total
[tex]\mathbf{10 + 3d = 19}[/tex]
Rewrite the above equation as:
[tex]\mathbf{3d + 10 = 19}[/tex]
Hence, the model that represents the situation is: [tex]\mathbf{10 + 3d = 19}[/tex]
