A student cost for last semester at her community college was $3000. She spent $540 of that on books. What percent of last semester’s college costs was spent on books? Please give explanation
Hi there! We can set up a ratio to model the problem... 540/3000 = x/100 Now, just cross multiply and solve for x. 54000 = 3000x x = 18 Therefore, 18 percent of last semester's college costs was spent on books. Hope this helped and have a great day!
