A theatre sells 135 tickets at £10 each and n tickets ar £13 each. Write down a formula for the total cost P, in £ of the tickets
Let T be the number of tickets sold at £10 each and n be the number of tickets sold at £13 each. The total cost P, in £, of the tickets can be calculated using the formula:
P = (10 * T) + (13 * n)
To calculate the total cost of the tickets, we can create a formula based on the number of tickets sold.
Let's say the number of tickets sold at £10 each is a and the number of tickets sold at £13 each is n - a (since there were 135 tickets sold in total).
The cost of tickets sold at £10 each can be calculated as 10 * a, and the cost of tickets sold at £13 each can be calculated as 13 * (n - a).
Therefore, the formula for the total cost P of the tickets would be:
P = 10 * a + 13 * (n - a)
