Jim and Paula jointly purchase the half sausagehalf veggie pizza for $21. Suppose that Paula values veggie pizza three times as much as she values sausage pizza. Find the dollar value to Paula of each of the following pieces of pizza:
a. The veggie half of the pizza
b. The sausage half of the pizza

V = Paula's value of veggie portion.
S = Paula's value of sausage portion
V + S = 21
V = 3S
4S = 21
(b) S = $5.25
(a) V = 15.75
