Samuel is going to the cinema with his brother, Kevin. They both have a total budget of $20 for their outing. Samuel buys his $14 ticket, then spends $6 on drinks and food. Kevin buys his ticket, then spends $2 on drinks. They have both used their entire budget. How much did Kevin spend on food?
Thoughts? Step-by-step reasoning:
We know Kevin bought a ticket and drinks, and this cost him 14 + 2 = 16 dollars. Since Kevin spent his entire budget, his food must have cost 20 16 = 4 dollars.
Thus, the answer is 4.
