“The world is a book, and those who do not travel only read one page.” -St. Augustine

Every kind of travel requires some planning, especially your mode of travel and expenses, and that kind of planning will always require math. With our kids’ math programs students can practice their elementary school math skills such and addition, subtraction, multiplication and division in a fun and interesting real-life way. Math help for kids doesn’t only take place in the classroom, it’s important to let children know that math is involved in every part of life!

So here we go...are you ready to plan a vacation? Give this week’s word problem challenge a try. See if you can help Lina and Thomas plan their vacation to San Francisco. Be sure to check back tomorrow to compare your solution to ours. And let us know in the comments where you’d want to take your vacation!

Question: Lina and Thomas are taking a vacation to San Francisco. Flights to San Francisco cost \$250 per ticket. Return flights cost \$325 per ticket. Lina and Thomas have a coupon for 50% off the cost of a single one-way ticket. What is the least they could spend on airfare before tax?

Solution: To spend the least possible amount on their airfare, Lina and Thomas would need to use the coupon on one of the most expensive tickets. So, if they get 50% off a \$325 ticket, one of those tickets is reduced to \$325 ÷ 2 = \$162.50. That means that the least Lina and Thomas could spend on airfare is \$250 + \$250 + \$325 + \$162.50 = \$987.50.

Before I came to Mathnasium, I could sum up everything I felt about math in one word: 'EVIL!' I hated math. ... Mathnasium has been my safe haven. They truly have shown me the light when it came to addressing my fear and provided me with the tools that I need to rebuild my prior knowledge so that I won't forget it. Math is no longer a subject I shy away from but it is a subject I can boldly accept and understand.
