A ticket to a movie cost t dollar and there is a 15% tax on each ticket.
Write an expression in terms of t to show the total cost.
The tax on each ticket is calculated by multiplying the ticket price (t) by 15% (or 0.15). Therefore, the total cost (including tax) is obtained by adding the ticket price and the tax:
Expression: t + (0.15t) = t(1 + 0.15)
