Afood truck sells salads for $6.50 each and drinks for $2.00 each. the food truck’s revenue from selling a total of 209 salads and drinks in one day was $836.50. how many salads were sold that day? a) 77 b) 93 c) 99 d) 105

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
s + d = 209
s = 209 - d

Plug in the values. 

6.5 (209 - d) + 2d = 836.5

1358.5 - 6.5d + 2d = 836.5
-4.5d = -522
d = 116

s = 209 - 116
= 93
