Q. Raj's catering company is serving an event for

35

guests. Each guest will choose either a salad or a bowl of soup.

\newline

1

. Write an equation that represents how many total salads Raj needs to prepare

(s)

when

b

guests choose a bowl of soup.

\newline

2

. How many salads does Raj need to prepare if

21

guests choose a bowl of soup? salads

Write Equation: $\newline$ Step $1$ : Write the equation for total salads needed. $\newline$ $s = 35 - b$
Substitute Value: $\newline$ Step $2$ : Substitute $b = 21$ into the equation. $\newline$ $s = 35 - 21$
Calculate Number: $\newline$ Step $3$ : Calculate the number of salads. $\newline$ $s = 14$
