They ordered one pizza and 5 large drinks, the pizza cost $15 and the total cost was $26.75, so the cost of one large drink is:
[tex]\begin{gathered} W\text{e call x the cost of one large drink:} \\ total\text{ cost = cost of one pizza + 5 }\cdot\text{ cost of one large drink} \\ 26.75=15+5\cdot x \\ 5\cdot x=26.75-15 \\ 5\cdot x=11.75 \\ x=\frac{11.75}{5}=2.35 \end{gathered}[/tex]So, one large drink cost $2.35
