Lewis found 4 more items on the scavenger hunt than Samantha. Samantha found four times the amount of items than Tanya who was only able to find 4 items. How many items did Lewis find? Let's answer step by step:
Samantha found 4 times the amount of items as Tanya’s 4 items so Samantha found 4 * 4 = 16 items. Lewis found 4 more items than Samantha who found 16 so he found 4 + 16 = 20 items. The answer: 20.
