Question

A caterer charges an initial fee of $120 plus $5 per guest. How many guests can you invite if you can afford topay the caterer a total of $430? Write an equation and solve.

Answer 1

equation is:

`120+5x=430`

where x = guest

then solve for x:

`\begin{gathered} 120+5x=430 \\ 120+5x-120=430-120 \\ 5x=310 \\ (5x)/(5)=(310)/(5) \\ x=62 \end{gathered}`

answer: 62 guest
