Louie made $400 in the school fundraiser. he sold $125 worth of chocolate bars and he sold 50 rolls of gift wrap at a certain amount per roll. how much did each roll of gift wrap cost? (show work)

What you have here is a simple algebraic equation. So, what you have to do is take out the numbers they give you and put it into an equation.

So let us refer to rolls of gift wrap as 'x'. So, you need 50x + $125 (from the chocolate) to = $400 in total sales. The equation you get is

50x + 125 = 400

The next step is to subtract 125 from both sides making it:

50x = 275

Now you divide both sides by 50 to get x as a single variable:

X = 5.50

So each roll of wrapping paper costs $5.50.

he agrees with the monk's positions.

for this case, we must find the number of deaths per day of the year 2015, in automobile accidents, knowing that 32,400 people died.

knowing that the year 2015 had 365 days we have the following division:

where "x" represents the number of deaths per day.

rounding off we have:

approximately, 89 people per day died in 2015

answer:

89 people per day
