40 percent of the cookies can be shown with the equation 40x .90, this makes 36, so Kylie bring in 36 cookies.
If you having trouble with percentages I recommend using Khan Academy. It’s an website that’s free with short videos about everything you can imagine, they aren’t long and have practice sheets you can do. Percentages can be very important in higher math so recommend taking like 5 min and checking a video.
Hope this helps! Please make me the brainliest, it’s not necessary but appreciated, I put a lot of effort and research into my answers. Have a good day, stay safe and stay healthy.
