15.75+17.50
46.24 minus answer in the top

What we know:
Medium pizza(m)=15.75
Large pizza(l)=17.50
Small pizza=s
m+l+s=46.24

m+l+s=46.24
(15.75)+(17.50)+s=46.24      substitution
33.25+s=46.24                      like terms
33.25-33.25+s=46.24-33.25  additive inverse
s=12.99

The small pizza (s) is $12.99.
