Final answer:
If a woman's hCG level is 240 on Monday and it doubles every 48 hours, then by Wednesday her hCG level should be approximately 480.
Step-by-step explanation:
The question pertains to human chorionic gonadotropin (hCG), which is a hormone produced during pregnancy. According to the information provided, if a woman's quantitative hCG level is 240 on Monday, and assuming that her hCG levels double every 48 hours, we can predict what her hCG level should be by Wednesday. To calculate this, we can simply double the hCG level of 240 to predict the level for Wednesday.
So, 240 multiplied by 2 equals 480. Therefore, if her hCG level was 240 on Monday, by Wednesday her hCG level should be approximately 480.
