Right Thomas, let's go. a) Step 1: Calculate the total cost of 18 cheapest pens. The cost of one pen is 27p. Total cost = 18 × 27p = 486p Step 2: Convert the payment to pence. Lottie pays with a £10 note. 10 = 1000p Step 3: Calculate the change Lottie should get. Change = 1000p - 486p = 514p Convert the change back to pounds. 514p = 5.14 The change Lottie should get is 5.14. b) If Lottie buys 18 of the more expensive pens, the total cost of the pens will be higher than if she bought the cheapest ones. Since she still pays with a £10 note, a higher total cost means that the amount of change she receives will be less. Send me the next one 📸
