Answer:
1) Papa Ron's(60$ per shift)
2) Little Squeezer's(3$ per pizza)
3) Little Squeezer's
Explanation:
1) A shift's pay is money given for simply entering the workplace(at least in this problem!) So it would be money given whether Tony has delivered pizzas or not. It would be numerically equal to his pay when he doesn't deliver any pizzas.
Bombino's offers 56$ per shift(stated in Q),
Little Squeezer's offers 48$ when he has delivered no pizzas, thus it must be his pay per shift.
Pizza Tent offers 52$ when he has delivered zero pizzas(substitute
p
=
0
in the given function S)
The graph shows that Papa Ron's offers 60$ when no pizzas are delivered. This is clearly the best pay per shift. (when
x
=
0
,
y
=
60
)
2) Bombino's: 2.5$ per pizza(stated)
Little Squeezers gives 6$ more than his default pay(which he would get even if he didn't deliver anything) when Tony has delivered 2 pizzas. Thus it gives 3$ per pizza.
Pizza Tent gives 2.75$ per pizza. This can be inferred from S.
S
=
2.75
p
+
52
Here, 52 is his default pay. He gets 2.75$ for each pizza delivered, as it is the coefficient of
p
.
Papa Ron's pay per pizza can be calculated by finding the slope of the line in the graph.

Here, I take the points (64, 2) and (60, 0).

Thus the pay is 2$ per pizza delivered. For simplicity, I will define Papa Ron's pay as a function
R
=
2
p
+
60
(Notice that 2 is the slope and 60 is the base pay)
Clearly, Little Squeezer's offers the most per pizza.
3) To figure this question out, we will need to find pay when Tony delivers 20 pizzas for each restaurant.

Little Squeezer's pays

Pizza Tent pays

Papa Ron's pays

So, Little Squeezer's is the company that pays best when Tony is delivering over 19 pizzas.
