inks in one day was $836.50. if the truck sold a total of. 116 drinks
how much salads were sold that day?
2 answers:
S = # of salads
d = # of drinks
$6.5s + $2d = $836.5
s + d =209
1. Isolate a variable.
s = 209-d
2. Plug in.
6.5 (209-d) + 2d = 836.5
1358.5 - 6.5d + 2d = 836.5
-4.5d = -522
d = 116
<span>s = 209 - 116 = 93</span>
116*2=232
and 232-836.5=604.5 and 604.5/6.5=93 so 93 salads were solo that day
