• A. $77$
• B. $93$
• C. $99$
• D. $105$

Answer 1

Answer: (B)

$93$

Let $s$ be the number of salads sold.
Then number of drinks sold $=209-s$
Since the earning was $836.50$, we have
$6.5s+2(209-s)=836.5$
$\Rightarrow 6.5s+418-2s=836.5$
$\Rightarrow 4.5s=418.5$
$\Rightarrow s=93$
Thus, $93$ salads were sold.
