[Question]In seven years, Talia will be 20 years old. Talia's mom is currently three times as old as Talia is today. In three years, Talia's father will be the same age as Talia's mom is today. Currently, how many years old is Talia's father?
[Answer]In seven years, Talia will be 20 years old, and therefore Talia is currently 20 - 7 = 13 years old. Talia's mom is currently three times as old as Talia is today, or 3 * 13 = 39 years old. If in three years, Talia's father will be the same age as Talia's mom is today, then Talia's father is currently 39 - 3 = 36 years old. The answer is 36.
Q: A wheel on a certain machine makes 6 turns every 30 seconds. How many turns does it make in two hours?
A: Since there are 60 seconds in 1 minute, then there are 60 / 30 = 2 sets of 30 seconds in a minute. So a wheel makes 6 x 2 = 12 turns in 1 minute. Since there are 60 minutes in 1 hour, then a wheel makes 12 x 60 = 720 turns in an hour. Therefore, the wheel makes 720 x 2 = 1440 turns in 2 hours. The answer is 1440.
Question: Julio receives a $1 commission for every customer that buys in Edgars Fashion Store. The store sells to 35 customers in the first week, twice as many in the second week, and triple as many as the first week in the third week. If he receives a salary of $500 for the 3 weeks and a bonus of $50, how much in total does he earn for the 3 weeks?
Answer: The number of customers who buy in the second week is 35 customers * 2 = 70 customers. The number of customers who buy in the third week is 35 customers * 3 = 105 customers. The total number of customers who buy during the 3 weeks is 35 customers + 70 customers + 105 customers = 210 customers. The total commission he receives is 210 customers * $1 / customer = $210. The total income he earns is $210 + $500 + $50 = $760. The answer is 760.
[Question]Carter has a jar with 20 green M&Ms and 20 red M&Ms. He eats 12 of the green M&Ms, then his sister comes and eats half the red M&Ms and adds 14 yellow M&Ms. If Carter picks an M&M at random now, what is the percentage chance he'll get a green M&M?
[Answer]First find the final number of green M&Ms by subtracting 12 from the starting number: 20 M&Ms - 12 M&Ms = 8 green M&Ms. Then find the final number of red M&Ms by dividing the starting number by half: 20 M&Ms / 2 = 10 red M&Ms. Then find the total number of M&Ms at the end by adding the number of red, green and yellow M&Ms: 8 M&Ms + 10 M&Ms + 14 M&Ms = 32 M&Ms. Then divide the number of green M&Ms by the total number of M&Ms and multiply by 100 to find the percentage chance Carter gets a green M&M: 8 M&Ms / 32 M&Ms * 100 = 25%. The answer is 25.
Q: Ofelia joined a saving challenge wherein she has to save twice the amount she saved from the previous month. In January, she saved $10. How much is she going to save in May?
A: Ofelia saves $10 x 2 = $20 in February. She will save $20x 2 = $40 in March. She will save $40 x 2 = $80 in April. Thus, she will save $80 x 2 = $160 in May. The answer is 160.
Question: Wendy went to the dentist for a cleaning, two fillings, and a tooth extraction. The dentist charges $70 for a cleaning and $120 for a filling. Wendy’s dentist bill was five times the cost of a filling. What did Wendy pay for the tooth extraction?
Answer:
Wendy’s dentist bill was 5 * $120 = $600. She got two fillings at a cost of 2 * $120 = $240. Thus, Wendy paid $600 - $240 - $70 = $290 for the tooth extraction. The answer is 290.
