It all started at my home when I was a curious kid. I can say Maths runs through my veins as my mother is a Maths teacher. Maths problems used to fascinate me a lot since I was a kid.\nBack in Elementary School, I began learning the basics of math like adding, subtracting, and shapes. My teachers saw my interest and encouraged me to explore more. As I moved to High School, math got more exciting with stuff like trigonometry, calculus, and fancier equations. I joined math clubs, made friends who loved math and got better at solving tough problems.\nThen came University, where math turned into a whole new level of amazing. I did my Graduation in Science (with Physics, Chemistry, and Maths as majors) and then completed my Master's (Post Graduation) with Mathematics as my major from Guru Nanak Dev University. My professors taught me advanced topics like Complex analysis, Abstract Algebra, Numerical analysis, and many more and I loved every moment of it. Learning became an adventure.\nAfter finishing university, I started using math in internships and jobs. I worked in a school as a PGT (Post graduate teacher) for a year and then I got the opportunity to tutor international students. I received an International Tutoring certificate as well. And after that, I came to know about the wonderful platform \"MATHMASTER\" where I'm currently working. I am grateful that Mathmaster provided me with a wonderful opportunity to harness and apply my skills in a truly effective manner. It provided me an opportunity to share my knowledge with students and help me improve my problem-solving skills. It's awesome to see how math could solve real problems and make a difference.\nMy journey with maths has been incredible. From those early math puzzles to tackling complex theories, I've grown so much. My maths journey has been amazing. From curious kid to university explorer, I've learned that math is everywhere and can be so much fun. I'll keep using my math skills to make the world a better place and inspire others to embrace the magic of numbers. I hope my story inspires you to never stop exploring because math is a journey that never really ends.",4.5,115,{"data":230},{"questions":231},[232,236,240,244,248,251,254,258,262,266,270,274,278,282,286,290,294,298,302,306],{"id":233,"category":28,"text_question":234,"slug":235},532000,"A sample is chosen from a population with y = 46, and a treatment is then administered to the sample.

Currently they are charging $50 for an adoption fee. Unfortunately they just pulled this number out of the air and do not know why they are charging this amount. They would like to charge an amount that covers all the adoption costs – both the variable costs for adoptions as well as the fixed cost for the kennel portion of the Humane Shelter operations. We can help them by doing a breakeven analysis.\r\n\r\nDuring a client meeting we gathered these facts. There are 2 part-time employees that each earn $1000 per month. The utilities for the kennel area (water, electricity) are $200 per month. The average food cost for animals in the kennel is $800 per month. In addition, each animal that is adopted receives a rabies vaccination that costs $4 and is micro-chipped that costs $6. \r\n\r\nAt the current cost of $50, how many animals must be adopted to break-even?\r\nWhat would break-even be at a $60 adoption fee? \r\nWhat would break-even be if the fee were lowered to $40?\r\nThe newspaper has suggested that the Humane Society advertise to increase pet adoptions. The package that they have recommended costs $1000 for a very small ad run every day for a month.
