Question: 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?
Answer with step-by-step thinking: 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.
So the answer is 160.

Question: Jorge has an equal number of baseball cards as Matias, who has 6 fewer cards than Carlos. If Carlos has 20 baseball cards, what is the total number of baseball cards the three have?
Answer with step-by-step thinking: If Carlos has 20 cards, Matias has 20 - 6 = 14 baseball cards. Since Matias and Jorge have the same amount of baseball cards, the total number of cards the three have is 14 + 14 + 20 = 48 cards.
So the answer is 48.

Question: Bill is buying healthcare on an exchange. The normal monthly price of the plan he wants is $500. The government will pay for part of this cost depending on Bill's income: 90% if he makes less than $10,000, 50% if he makes between $10,001 and $40,000, and 20% if he makes more than $50,000. Bill earns $25/hour and works 30 hours per week, four weeks per month. How much will Bill spend for health insurance in a year?
Answer with step-by-step thinking:
First find how much money Bill makes every week by multiplying his hourly rate by the number of hours he works each week: $25 / hour * 30 hours / week = $750 / week. Then multiply that number by the number of weeks per month to find his monthly earnings: $750 / week * 4 weeks / month = $3,000 / month. Then multiply his monthly earnings by the number of months in a year to find his annual income: $3,000 / month * 12 months / year = $36,000 / year. This income means Bill gets a 50% monthly healthcare subsidy from the government. Multiply the cost of the premium by 50% to find the monthly cost Bill pays: $500 / month * .5 = $250 / month. Finally, multiply Bill's monthly cost by the number of months in a year to find his annual cost: $250 / month * 12 months / year = $3,000 / year.
So the answer is 3000.
