The demand for your hand-made skateboards, in weekly sales, is q=-5p+600 if the selling price is $p. You are prepared to supply q=5p-400 per week at the price $p. What price should you sell your skateboards for so that there is neither a shortage nor a surplus?

Someone please help :(

2 answers

you want supply to equal demand at price p.

-5p+600 = 5p-400
10p = 1000
p = 10
-5p+600 = 5p-400
10p = 1000
p = 100
