Question

I need help with number 5 please

Answer 1

C(t) = $2t + $8

This tells us that the basic cost of the pizza is $8, with no toppings, and that each topping costs an additional $2.

To graph this, plot a dot at (0,$8).  Now move y our pencil point 1 unit to the right and then 2 units up.  Plot a dot at this new location.  Now draw a straight line connection (0, $8) and this new location (which is   (1, $10)  ).
