<span>You are selling the following items.
=> lemonade = $1.50
=> kettle corn = $3
=> hotdog = $2.50
=> p = number of people
Now, we need to write the expression of this given equation:
=> Amount = p(1.50 + 3 + 2.50) or Amount = p(1.50) + p(3) + p (2.50)
In where p is the number of people who will buy your food and will be
multiplied to the amount of each food you’re selling to be able to get the
total amount of money you will have.

Answer:
x=-7, y=-9. (-7, -9).
Step-by-step explanation:
-3x+4y=-15
4x-y=-19
---------------
y=4x-(-19)
y=4x+19
-3x+4(4x+19)=-15
-3x+16x+76=-15
13x=-15-76
13x=-91
x=-91/13
x=-7
4(-7)-y=-19
-28-y=-19
y=-28-(-19)
y=-28+19
y=-9
Answer:
see explanation
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = 
x + 4 ( multiply through by 2 to clear the fraction )
2y = x + 8 ( subtract 8 from both sides )
2y - 8 = x
Change y back into terms of x with x = 
(x) , then
(x ) = 2x - 8
(4) = 2(4) - 8 = 8 - 8 = 0
