Question

a ski shop has a markup rate of 50% find the selling price of skis that cost the store owner $300. tell me how you got the answer

Answer 1

If nthe shop has a mark up rate of 50% and they cost 300 to buy you multiply 300 by 50%  convert 50% to decimal
so you do .5*300=150
then you add 150 to 300 which means that the shop sells the skis for 450 dollars.
