Mallie is investing in some stocks. When she followed one of the stocks over a five-day-period, she saw these increases and decreases: +3.45, -5.67, -7.80, +4.67, +13.45. Round these to the nearest integer then estimate the increase or decrease over the 5 days. I got an increase of 8 and it was incorrect. What am I doing wrong?
