A mean average of 60 on 7 exams is needed to pass a course. on his first 6 exams, Adam received grades of 46,74,70,59,66 and 72. if his lowest grade of the exams already taken is to be dropped,what grade must he receive on his last exam to pass?

I agree with Steve.

To find out the grade Adam needs to pass the course, we first need to calculate the average of his first 6 exams (without including the lowest grade). Here's how you can do it:

1. Add up the grades of the first 6 exams: 46 + 74 + 70 + 59 + 66 + 72 = 387.

2. Find the lowest grade among the first 6 exams. In this case, it's 46.

3. Subtract the lowest grade from the total: 387 - 46 = 341.

4. Divide the remaining total by the number of remaining exams (6 in this case, as we dropped one exam): 341 / 6 = 56.83 (approximately).

Now, Adam needs an average of 60 on 7 exams to pass the course. To calculate the grade he needs on his last exam, we can use the following steps:

5. Multiply the desired average (60) by the total number of exams (7): 60 * 7 = 420.

6. Subtract the sum of the grades from the first 6 exams (387) from the desired total (420): 420 - 387 = 33.

Therefore, to pass the course, Adam needs to receive a grade of at least 33 on his last exam.
