Lyndie is exercising by running up and down the stairs in her home. Last week her best rate was 88 steps in 5 minutes. She wants to improve upon that score by 10% this week. She wrote the following formula to determine how many steps she would have to run in t minutes. S = (88/5)t + .10(88/5)t, where S=Number of steps and t = time in minutes. Which of the following expressions makes the same statement in a simpler manner?
