[Question]A candy store uses food colouring in various candies. Each lollipop uses 5ml of food colouring, and each hard candy also needs food colouring. In one day, the candy store makes 100 lollipops and 5 hard candies. They do not use food colouring in anything else. The store has used 600ml of food colouring by the end of the day. How much food colouring, in millilitres, does each hard candy need?
[Answer]In total, the lollipops needed 5ml of food colouring * 100 lollipops = 500ml of food colouring. This means that the hard candies needed 600ml total food colouring – 500ml food colouring for lollipops = 100ml of food colouring. So each hard candy needed 100ml of food colouring / 5 hard candies = 20 ml of food colouring. The answer is 20.

Question: A salesman bought a case of 48 backpacks for $576. He sold 17 of them for $18 at the swap meet, 10 were sold to a department store for $25 each. If the remainder were sold for $22 each. How much was the salesman's profit?
Answer: The salesman sold 17 bags for 17 bags x $18 / bag = $306. He sold 10 more for 10 bags x $25 / bag = $250. Thus far he has sold 17 bags + 10 bags = 27 bags. Therefore he sold 48 bags - 27 bags = 21 bags for $22 each. 21 bags were sold for 21 bags x $22 / bag = $462. In total the salesman made $306 + $250 + $462 = $1018. The salesman made $1018 - $576 = $442 in profit. The answer is 442.
[Question]A hairstylist charges $5 for a normal haircut, $6 for a special haircut, and $8 for a trendy haircut. If he cuts 5 normal haircuts, 3 special haircuts, and 2 trendy haircuts per day, how much money does he earn per week?
[Answer]The hairstylist earns $5 x 5 = $25 for a normal haircut per day. He earns $6 x 3 = $18 for a special haircut. And he earns $8 x 2 = $16 for a trendy haircut. So, the total amount he earns per day is $25 + $18 + $16 = $59. Therefore, a hairstylist earns $59 x 7 = $413 per month. The answer is 413.
[Question]Reynald is the head of the varsity department, and he bought 145 balls. Twenty were soccer balls. There were five more basketballs than the soccer balls. Twice the number of soccer balls were tennis balls. There were ten more baseballs than the soccer balls, and the rest were volleyballs. How many were volleyballs?
[Answer]
There were 20 + 5 = 25 basketballs. There were 2 x 20 = 40 tennis balls. And, there were 20 + 10 = 30 baseballs. So, there were 20 + 25 + 40 + 30 = 115 soccer balls, basketballs, tennis balls and baseball altogether.                      Therefore, Reynald bought 145 - 115 = 30 volleyballs,. The answer is 30.
