Solve by substitution. We begin by manipulating the second equation (solving for y).
2x+3y=13
4x-y=-2 => -y=-4x-2 => y=4x+2
Now substitute "4x+2" for y into the first equation because y=4x+2.
2x+3y=13 becomes 2x+3(4x+2)=13
Now solve for x.
2x+3(4x+2)=13
2x+12x+6=13
14x=7
x=1/2
Now we can solve for y because we know what x is.
y=4x+2 => y=4(1/2)+2 = y=4
answer: x=1/2, y=4, intersection point (1/2,4)
55+p=105
subtract 55 from both sides
p=50

Step-by-step explanation:
M is the membership and b is billy
Table is attached below
From the table we can see that the Lemon cost is equal to 35% of the expenses
Let the expense be x, Lemons cost is 70
Lemon cost = 35% * x
70 = 35% * x ( 35% =
= 0.35)
70 = 0.35 * x
x = 
x= 200, Expense = $200
Given : Profit percentage is 15%=
= 0.15
Profit = profit percentage * Expense
Profit = 0.15 * 200 = 30
So profit = $30
