Respuesta :
Answer: 18
Step-by-step explanation:
To find the number of times out of 45 Evelyn is on time for class, we need to find 40 percent of 45. 40 percent of 45 is equivalent to writing 0.4 x 45. Since 0.4 x 45 equals 18, we can estimate that Evelyn will be on time to class about 18 times out of 45
