Given data
We are given that
Large lemonade= $6
Small lemonade= $4
Total amount = 6+4= $10
He keeps 50% of the total
= 50/100*10
=0.5*10
= $5
Hence he will keep $5
In order to find the equivalent expression, let's use the following property:

In other words, when subtracting a negative number, we can just add the corresponding positive number, that is, switch the two negative signs for a positive sign.

Yes, she is correct.
Step-by-step explanation:
y = kx is direct variation
15 = k*-3
k = -5.
So the equation of variation is
y = -5x
When x = -4:
y -5*-4 = 20.
