Solutions
There are two equations in the system of equations in this problem.
Let x = lemonade and y = hot dogs
Equation # 1
x + y = 86
This says that t<span>he vendor sold 86 items.
</span>Equation # 2
2x + 5y = 330
= $2 for each lemonade
= $5 for each hot dog.
= total amount earned is $330.
Only these two equations are true and needed.

The easiest way is to round down to 40 and take 50% of that, which is 20. The actual answer is 20.5.
Step-by-step explanation:
4x+(x+5)=20
5x+5=20
5x=15
X=3
