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.
