Afamily earns $523 from the yard sale. they pay 45 in advertising fees. what is the family profit from yard sale?

$478

Step-by-step explanation:

To calculate the profit, we have to subtract the expenses from the revenues.

P = Revenues - expenses

We know the family gained $523 from the yard sale.

We also know they had to pay $45 for advertising.

So, the net different is the profit for the family:

P = $523 - $45 = $478.

That was a very good yard sale!, I hope mine went that well.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
