In December, Gyu Ha could type 35 words per minute. In March, he could type 42 words per minute. What is his percent of change in the number of words per minute he could type from December to March?
Step-by-step explanation: you just multiply 35 bye different percent and obviously more than 50 is too much in less than 10 is too little so just multiply from numbers that you know are close and from 35 to 42 is seven so once you multiply those percent by 35 you have to get seven as your answer
