Hi i have a "challenge" problem that i have to solve. I have no idea how i should write the equation to solve this. I don't understand how I can make an equation to answer both parts of the question. Should i use 2 variables? One for price and one for the number of magnets produced? Please take a look.

The question is:your company makes fridge magnets. The materials for each magnet is $0.14. Your company has additional expenses of $27 000 year. The per-magnet cost is . If your company can make and sell twice as many magnets next year as this year, the per-magnet cost will be reduced by $0.90.How many magnets is your company making and selling this year?

Thanks.
