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:

$\begin{gathered} 120+5x=430 \\ 120+5x-120=430-120 \\ 5x=310 \\ \frac{5x}{5}=\frac{310}{5} \\ x=62 \end{gathered}$

answer: 62 guest
