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
</span>

Let the number of packages of hot dogs be D, and the number of packages of hamburgers be H. We can set up the equations:
1.60D + 5H = 23
D + H = 8 ---> which we can subtract D on both sides and get: H = 8 - D
1.6D + 40 - 5D = 23, -3.4D = -17, D = 5. The number of packages of hot dogs we buy are 5.
Now, we plug that into D + H = 8, and get 5 + H = 8. Subtracting by 5 on both sides of the equation, we get H = 3. So the number of packages of hamburgers we buy are 3.
