A photo app has 5 filters, 4 frames, and 3 stickers. If you may choose no sticker or exactly one sticker, how many different looks can be made?

Answer and explanation

Correct answer: 80 looks

There are 5 × 4 = 20 filter-and-frame choices. The sticker choice has 4 possibilities: no sticker or 1 of the 3 stickers. Thus, 20 × 4 = 80 looks.
