Respuesta :
The club is making posters to raise money.
The printer charges a base fee of $270 and $2 per poster for supplies.
Suppose the club gets x number of posters printed.
The cost of printing x posters with 270 fixed charges shall be
Cost = 2x + 270
Now each poster sells for $5
So selling price of x posters = $5x
Now selling price - cost price = profit
5x - (2x+270) = 300
5x - 2x - 270 = 300
3x -270 = 300
Adding 270 on both sides
3x = 300 + 270
3x = 570
Dividing by 3 on both sides
x = 190
The club must see 190 posters to make a profit of $300.
Profit is the difference between the selling price and cost price. For a profit of $300, the number of posters that must be sold is 190.
What is the linear system?
A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
A club is making posters to raise money.
The printer charges a base fee of $270 and $2 per poster for supplies.
A person sells each poster for $5.
Let x be the number of posters. Then the cost price and selling price is given by
Cost price = 2x + 270
Selling price = 5x
The posters must be sold to make a profit of $300. Then
We know that the profit is given by
Profit = selling price – cost price
Put all these values to get the value of x.
5x – (2x + 270) = 300
5x – 2x – 270 = 300
3x = 300 + 270
3x = 570
x = 190
For a profit of $300, the number of posters that must be sold is 190.
