A theme park sells tickets online. A ticket costs 24 pounds. There is a three-pound charge for buying tickets. Which of these shows how to calculate the total cost in pounds? Tick one. Number of tickets times three plus 24. Number of tickets times 24 plus three. Number of tickets plus three times 24. Number of tickets plus 24 times three.

The first really important piece of information in the question tells us that a ticket costs 24 pounds. If we use 𝑛 to represent the number of tickets, we would find the cost of tickets by multiplying the number by 24. The first calculation is therefore incorrect. We need to multiply the number of tickets by 24, not three. So this doesn’t show us how to calculate the total cost in pounds.

The second calculation looks more promising, the number of tickets multiplied by 24. We know there is a three-pound charge for buying tickets. This tells us that we can find the total cost by multiplying the number of tickets by 24 and then adding the three-pound charge. Well, we can see the second calculation asks us to multiply the number of tickets by 24 and then add three.

We need to tick the second box. We can calculate the total cost in pounds by multiplying the number of tickets by 24 and then adding the three-pound charge.
