Question

The students in Naomi's class sold calendars for a fund-raiser this year and last year. This year, the selling price of each calendar was 13.25. The price this year represents 6% more than the selling price of each calendar last year. What was the selling price of each calendar last year ?

Answer 1

We'll use the variable x to represent last year's price. First, we have to set up an equation:

`.06x+x=13.25`
We get this equation because $13.25 is 6% MORE than last year's price, meaning we need to add the original price to the increase. Next, we combine like terms and solve for x:

`.06x+x=13.25 \\ 1.06x=13.25 \\ (1.06x)/(1.06) = (13.25)/(1.06) \\ x= 12.50`

Last year's price was $12.50.

Hope this helps!
