Answer this question: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?
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.

Answer this question:Kristy baked cookies because her friends are coming over to her house. She ate 2 of them and gave her brother 1 cookie. Her first friend arrived and took 3 cookies. The second and third friends to arrive took 5 cookies each. If there are 6 cookies left, how many cookies did Kristy bake?
There were 6 + 5 = 11 cookies left before the third friend took 5. There were 11 + 5 = 16 cookies left before the second friend took 5. There were 16 + 3 = 19 cookies left before the first friend took 3. There were 19 + 1 = 20 cookies left before Kristy gave 1 cookie to her brother. There were 20 + 2 = 22 cookies that Kristy baked.
The answer is 22.

Answer this question:5,000 people live in a small town. 2,000 males live in that town and the rest of the population are females. Thirty percent of the female population wears glasses. How many females wear glasses?
