Answer: 5 pizzas and 17 sodas were bought

Step-by-step explanation:

I don't have answers for a or b but I have them for c.

          Number of pizzas

      9.50n+1.25(3n+2)=68.75

         9.50+3.75n+2.50=68.75

           combine like terms

         13.25+2.5= 68.75

      subtract from both sides

     13.25=68.75-2.5

         13.35=66.25

            Divide

             n=5

         Number of sodas

        3n+2=3(5)+2=15+2=17
