Stacy has 32 berries. Steve takes 4 of Stacy's berries, and still has 7 less berries than Stacy started with. How many berries did Steve start with?
Let's think: Let x be the number of berries Steve started with. x + 4 = 32 - 7. x + 4 = 25. x = 21 berries.. The answer is: 21.

There were 349 pieces of candy in a bowl. Talitha took 108 pieces and Solomon took 153 pieces. How many pieces of candy remain in the bowl?

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?
Let's think: 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.

Tom spends $250 to buy gems in a game he plays. The game gives 100 gems for each dollar you spend. Since he bought so many gems he got a 20% bonus of more gems. How many gems did he end up with?
Let's think:
He bought 250 * 100 = 25000 gems. He got a 25,000 * .2 = 5,000 gem bonus. So he got a total of 25000 + 5000 = 30,000 gems.. The answer is: 30000.
