You buy 3 packs of snacks, and each pack contains 2 chips and 4 cookies. How many snacks did you buy in total?
= 3(2 + 4)
= (3 × 2) + (3 × 4)
= 6 + 12
= 18 snacks

A factory produces 25 boxes of parts, and each box contains 120 parts. Use the distributive property to find the total number of parts.
= 25 (100 + 20)
= (25 × 100) + (25 × 20)
= 2500 + 500
= 3000 parts
