Calum runs a nightclub and decides to run a disco night to attract different customers. He is planning the event and is calculating how much he can spend on each item without spending more than he has budgeted. He only needs to buy 4 disco balls and 10 boxes of food. Each box of food costs $25. Calum’s budget for the disco balls and food is $330. How much, in dollars, can Calum afford to spend on each disco ball?
Let's think: The food is going to cost Calum a total of 10 boxes of food * $25 per box of food = $250. This leaves $330 budget - $250 spent on food = $80 to spend on disco balls. Calum can therefore afford to spend $80 remaining budget / 4 disco balls = $20 on each disco ball.. The answer is: 20.

A bird watcher records the number of birds he sees each day. One Monday he sees 70 birds. On Tuesday he sees half as many birds as he did on Monday. On Wednesday he sees 8 more birds than he did on Tuesday. How many total birds did the bird watcher see from Monday to Wednesday?
Let's think: Monday:70. Tuesday:70 / 2 = 35. Wednesday:35 + 8 = 43. Total:70 + 35 + 43 = 148 birds.. The answer is: 148.

Beyonce releases 5 different singles on iTunes. Then she releases 2 albums that each has 15 songs and 1 album that has 20 songs. How many songs has Beyonce released in total?
Let's think: In her 2 albums, Beyonce releases 2 * 15 = 30 songs. In her next album, Beyonce releases 1 * 20 = 20 songs. Since each single is one song, Beyonce releases a total of 30 + 20 + 5 = 55 songs.. The answer is: 55.

John commissions an artist to make him a 9 by 13 drawing. A black and white drawing that size would cost $160. He wants a color drawing so that is 50% more expensive. How much did he pay?
