Michelle is selling notebooks to her classmates so they can be organized in Math class. • Each box contains 20 notebooks
• Each box of notebooks cost $30
Michelle wants to make a profit of $20. How much does she need to sell her notebooks to make a profit of $20?

chase is right because he already been to the swings and he know how far it will be to get there

step-by-step explanation:

can you put the picture up?

step-by-step explanation:

the answer is a if my teacher taught me correct

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
