[Question]Jay has decided to save money from his paycheck every week. He has decided that he will increase the amount he saves each week by 10 dollars. If he started by saving 20 dollars this week, how much will he have saved in a month from now?
[Answer]In one week he will have saved 20 + 10 = 30 dollars. In two weeks he will have saved 30 + 10 = 40 dollars. In three weeks he will have saved 40 + 10 = 50 dollars. At the end of week four, he will have saved 50 + 10 = 60 dollars. The answer is 60.
Q: Luna's monthly food budget is equal to 60% of her house rental budget while her phone bill budget is 10% of her food budget. If the total budget of house rental and food budget is $240, how much is Luna's total monthly budget to pay all those expenses?
A: Let x be Luna's house rental budget. The total budget for house and food rental is represented by the equation x + (60x / 100) = 240. The equation becomes 100x + 60x = 24000 after multiplying each term by 100 to get rid of the fraction. By combining like terms, the equation becomes 160x = 24000. Thus, the value of x is 24000 / 160 = 150 which represents the house rental budget. So, Luna's food budget is $240 - $150 = $90. Her phone bill budget is $90 x 10 / 100 = $9. Therefore, Luna's monthly budget for all those expenses is $240 (house and food) + $9 (phone) = $249. The answer is 249.
Question: Jean is a customer service rep and answered 35 phone calls on Monday. On Tuesday, she answered 46 and took 27 calls on Wednesday. On Thursday she answered 61 calls and finished off answering 31 calls on Friday. What's the average number of calls she answers per day?
Answer: During the week she answered 35 on Mon, 46 on Tue, 27 on Wed, 61 on Thurs and 31 on Fri for a total of 35 + 46 + 27 + 61 + 31 = 200 calls. She answered 200 calls over 5 days so on average, she answered 200 / 5 = 40 calls a day. The answer is 40.
[Question]Celina enjoys hiking in the mountains. Due to a lack of proper equipment, she decided to order a new pair of boots, a flashlight, and a special hoodie. The hoodie cost $80 and the flashlight was only 20% of that price. The pair of boots cost was $110, but due to a special promotion, Celina was able to buy them 10% cheaper. How much did Celina spend in total on the above-mentioned equipment?
[Answer]The flashlight was 20% of the price of the hoodie, so 80 * 20 / 100 = $16. The promotion for a pair of boots was 110 * 10 / 100 = $11. So the pair of boots cost 110 - 11 = $99. Celina therefore spent 80 + 16 + 99 = $195 on the equipment. The answer is 195.
Q: 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?
A: 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. The answer is 3000.
