Question

Sam graduation picnic cost $13 for decoration plus an additional $5 for each attendee.at most how many attendees can there be if sam budgets a total of $33 for his graduation picnic?

Answer 1

Given:

The cost of graduation picnic = $13 for decoration plus an additional $5 for each attendee

Let the number of attendance = x

we need to find x when sam budgets a total of $33 for his graduation picnic

So,

`13+5x=33`

solve for x, subtract 13 from both sides:

`\begin{gathered} 13+5x-13=33-13 \\ 5x=20 \end{gathered}`

divide both sides by 5

`\begin{gathered} (5x)/(5)=(20)/(5) \\ \\ x=4 \end{gathered}`

So, the answer is:

The number of attendees = 4
