a. The cost of n tickets can be represented by the expression 9n.
b. With £108, you could buy 12 tickets.
1. The cost of a ticket for a football match is £9.
a) Write down an expression for the cost of n tickets.
The cost of n tickets can be represented by the expression 9n, where 9 represents the cost of a single ticket and n represents the number of tickets.
b) Solve an equation to determine how many tickets could be bought with £108.
Let's set up an equation to represent the total cost of tickets:
9n = 108
To solve for n, we can divide both sides of the equation by 9:
n = 108 / 9
Simplifying the expression, we get:
n = 12
Therefore, with £108, you could buy 12 tickets.
