Amaya scored 20 marks fewer in Maths than she scored in Arts. She also got 10 marks more in Social Studies than she got in Music. If she scored 70 in Music and scored 1/10 less in Maths, what's the total number of marks she scored in all the subjects?
Let's think: The total marks Amaya scored more in Music than in Maths is 1 / 10 * 70 = 7 marks. So the total marks she scored in Maths is 70 - 7 = 63 marks. If she scored 20 marks fewer in Maths than in Arts, then he scored 63 + 20 = 83 in Arts. If she scored 10 marks more in Social Studies than in Music, then she scored 70 + 10 = 80 marks in Social Studies. The total number of marks for all the subjects is 70 + 63 + 83 + 80 = 296 marks.. The answer is: 296.

Each week Carina puts 20 more seashells in a jar than she did the week before. If there are 50 seashells in the jar this week, how many will there be in a month?
Let's think: In one week there will be 50 + 20 = 70 seashells. In two weeks there will be 70 + 20 = 90 seashells. In three weeks there will be 90 + 20 = 110 seashells. In four weeks there will be 110 + 20 = 130 seashells.. The answer is: 130.

Jemma saw 7 grasshoppers on her African daisy plant. Then, hopping on the grass under the plant, she found 2 dozen baby grasshoppers. How many grasshoppers did Jemma find altogether?
Let's think: Jemma found 2 x 12 = 24 baby grasshoppers. In total, she found 24 + 7 = 31 grasshoppers.. The answer is: 31.

Jimmy is going to sell pizzas at the carnival to make some money. The carnival only gave him 7 hours to do so. He bought a 22kg sack of flour to make his pizzas and he takes 10 min to make each pizza for the customers. At the end of the 7 hours, he saw some flour was left. Knowing that each pizza needs 0.5kg of flour to make, how many pizzas can he make to bring home with the flour left?
Let's think:
Each hour Jimmy makes 60min ÷ 10min / pizza = 6 Pizzas. The number of total pizzas made equals 7 hours x 6 pizzas / hour = 42 pizzas. The amount of total flour used equals 42 pizzas x 0.5 kg / pizza = 21 kg. The amount of flour left equals 22 kg - 21 kg = 1 kg. The number of pizzas Jimmy can make is 1kg ÷ 0.5kg / pizza = 2 pizzas.. The answer is: 2.
