Answer this question:A clothing store sells 20 shirts and 10 pairs of jeans. A shirt costs $10 each and a pair of jeans costs twice as much. How much will the clothing store earn if all shirts and jeans are sold?
Twenty shirts amount to $10 x 20 = $200. The cost of each pair of jeans is $10 x 2 = $20. So 10 pairs of jeans amount to $20 x 10 = $200. Therefore, the store will earn $200 + $200 = $400 if all shirts and jeans are sold.
The answer is 400.

Answer this question:Ali has a store that sells fruits and vegetables. He puts 23 kg of kidney apples, 37 kg of golden apples and 14 kg of Canada apples on the shelves. By noon, 36 kg of apples were sold. What is the mass of apples that he has left?
You first have to calculate the total mass of apples he had on the shelves, so you add the three kinds of apples: 23 kg + 37 kg + 14 kg = 74kg. Since he sold 36 kg of apples, he still has: 74 kg – 36 kg = 38kg.
The answer is 38.

Answer this question:An ice cream vendor has 50 chocolate-flavored ice creams and 54 mango-flavored ice creams in his cart. If he sold 3/5 of the chocolate-flavored ice creams and 2/3 of the mango-flavored ice creams, how many total ice creams were not sold?
There were a total of 50 + 54 = 104 ice creams. There were 50 x 3 / 5 = 30 chocolate - flavored ice creams sold. There were 54 x 2 / 3 = 36 mango - flavored ice creams sold. A total of 30 + 36 = 66 ice creams were sold. So, 104 - 66 = 38 ice creams were not sold.
The answer is 38.

Answer this question:Lloyd, Mark, and Michael have their Pokemon cards collection. Currently, Mark has thrice as many cards as Lloyd but has 10 fewer cards than Michael. If Michael has 100 cards now, how many more cards should they collect so that all three of them will have a total of 300 cards?

Mark has 10 fewer cards than Michael so Mark has 100 cards - 10 cards = 90 cards. So, Lloyd has 90 cards / 3 = 30 cards. All three of them have 90 cards + 30 cards + 100 cards = 220 cards. Thus, they need to collect 300 cards - 220 cards = 80 more cards.
The answer is 80.
