[Question]Evie is collecting seashells while at the beach. Each day she collects her favorite 10 shells. At the end of 6 days, she gives 2 shells to her brother. How many shells does she have left?
[Answer]Multiply the number of shells collected each day by 6, to get the total number of seashells Evie has collected: 10 x 6 = 60 seashells. Subtract the 2 shells she gave her brother, to get the number of shells she has left: 60 - 2 = 58 seashells. The answer is 58.
Q: Mark got a 5% raise at his job. Before the raise, he earned 40 dollars per hour. He works 8 hours per day for 5 days per week. His old bills used to be 600 dollars a week but he decided to add a hundred dollar a week personal trainer. How much does he have leftover a week?
A: After the raise he earns 40 * 1.05 = 42 dollars an hour. He works 8 hours per day so earns 42 * 8 = 336 per day. He works 5 days per week so he earns 336 * 5 = 1680 a week. His expenses after adding the personal trainer are 600 + 100 = 700 a week. So he has 1680 - 700 = 980 left over. The answer is 980.
Question: Chad has 100 apples and each apple has different sizes and different price ranges. Each small apple cost $1.5, medium apple cost $2, and big apples cost $3. If Donny bought 6 small and medium apples and also 8 big apples, how much will Donny have to pay for all of it?
Answer: Donny was charged $1.5 x 6 = $9 for the small apples. He was charged $2 x 6 = $12 for the medium apples. And he was also charged $8 x 3 = $24 for the big apples. Therefore, Donny has to pay $9 + $12 + $24 = $45 for all the apples. The answer is 45.
[Question]Kenneth spent 10% of this earnings this week on a new joystick. If he is left with $405, how much were his earnings?
[Answer]Since Kenneth spent 10%, then he is left with 100% - 10% = 90% of his earnings. Since 90% of his earnings is worth $405, then 1% of his earnings is $405 / 90 = $4.50. Hence, Kenneth's earnings is $4.50 x 100 = $450. The answer is 450.
Q: Samuel bought 2 dozen doughnuts and Cathy bought 3 dozen doughnuts. They planned to share the doughnuts evenly with their 8 other friends. How many doughnuts will each of them receive?
A: Since 1 dozen is equal to 12, then Samuel has 2 x 12 = 24 doughnuts. While Cathy has 3 x 12 = 36. They both have 24 + 36 = 60 doughnuts together. There are 8 friends + 1 (Samuel) + 1 (Cathy) = 10 that will share the doughnuts. Thus, each of them will get 60 / 10 = 6 doughnuts. The answer is 6.
Question: Natalie's sister had 8 small diaries in her locker. Last summer she bought double the number of diaries she had and then lost 1/4 of what she had. How many diaries does Natalie's sister have now?
