Question

Jovita made 300 greeting cards. She sold 40% of the cards, gave 85% of the remaining cards to her friends, and kept the rest of the cards for herself. How many greeting cards did she keep for herself.

Answer 1

She  kept 27 for herself because 40% of 300 greeting cards is 120, so the remaining is 180 cards. 85% of 180 cards is 153 leaving you only 27 cards. to find the percent of something just multiply them for instance when trying to find 40% of 300 cards just multiply 300 by .4
