Question

I need help with this the a, b, c etc are not to circle you have to answer them individual.

Answer 1

decoration of the gym = $ 189.26

cost of security guard per hour = $52.50

Hours for the dance = 3 hours

deejay charges = $50.98 plus 23.50 per hour.

refreshement = $2.25 per student

Amount student council raised = $349.49

95 student will attend and share the cost of the dance

a.

cost of the security guard and deejay cost

`\begin{gathered} \text{deejay cost=50.98+23.50x} \\ x=\text{ number of hours} \\ \\ \sec urity\text{ cost per hour=\$}52.50x \\ \text{let x=number of hour} \\ \\ \cos t=\text{50.98+23.50x}+52.50x \\ \cos t=50.98+76x \\ x=3\text{ hours} \\ \text{ } \end{gathered}`

b.

`\begin{gathered} \cos t\text{ of security guard and d}eejay=50.98+76x \\ \cos t\text{ of security guard and d}eejay=50.98+76(3) \\ \cos t\text{ of security guard and d}eejay=\text{ \$}278.98 \end{gathered}`

c.

`\begin{gathered} \cos t\text{ of refreshment=2.25}*95 \\ \cos t\text{ of refreshment= \$}213.75 \end{gathered}`

d.

`\text{total cost for the dance=278.98+213.75+}189.26=\text{ \$}681.99`

e.

`\text{amount student ne}ed\text{ to collect from ticket sales=681.99-}349.49=\text{ \$}332.5`
