Create an equation to figure out how much salad was sold that day. S is for the number of salads. D is for the number of drinks.
$6.5s + $2d = $836.5
<span>s + d = 209
</span><span>s = 209 - d
Plug in the values.
</span>6.5 (209 - d) + 2d = 836.5
1358.5 - 6.5d + 2d = 836.5
-4.5d = -522
d = 116
<span>s = 209 - 116
= 93
