Question

Ticket was sold with fixed price of $70. A few more tickets were sold to cover extra expenses, after selling 10 tickets there was still a loss of $800.

Let P represent $ and ‘n’ tickets

Complete the equation for the relationship b/n net profit and number of tickets sold.

Answer 1

P = 70n -1500

Explanation:

Hi, the price of each ticket is $70. So, if after 10 tickets were sold

($70 x 10 = $700) there was still a loss of $800, the expression of the initial loss is:

Loss = ($70 x 10) + 800 = 700 +800 = $1500

To obtain the equation for the profit, we have to multiply the price of each ticket by the quantity (n) and subtract to that result the initial loss (1500):

Mathematically speaking:

P = 70n -1500
