Your friend asks you to go to the amusement park for a day. You'd like to go, but you need to find the total cost. You'll need to pay for a ticket and food, plus bus fare to get to the park and back. (Remember, you'll need to take the bus to the amusement park and home, so you'll need to double the cost of the ticket.) Write a formula that will help you determine your total cost.
