Question

The VMS math department includes the following teachers: Ruhland, Boyer, Tisor and Tuholsky. The team is ordering pizza to eat during their afternoon meeting with Mrs. Welch. They split one pizza and 5 large drinks. The pizza cost $15.00. They spend a total of $26.75. Write and solve the equation to find the cost of one large drink.

Answer 1

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:

`\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=(11.75)/(5)=2.35 \end{gathered}`

So, one large drink cost $2.35
