In order to graduate, a bo needs an average of 65 percent for his five major subjects. His first four grades were 55, 60, 65, and 65. What grade does he need in the fifth subject in order to graduate like a boss?
(55+60+65+65+x)/5=65
x=80
so on the fifth subject he needs an eighty.
65 * 5 = 325
55 + 60 + 65 + 65 = 245
325 - 245 = 80
He needs 80% for the last subject.
He needs a total of 5*65 = 325 points.
He has(55+60+65+65) = 245
He needs 325-245 = 80
If you want to set this up in equation form it will be
(55+60+65+65+x)/5 = = 65 and solve for x
Well, it looks like your "bo" is in a bit of a pickle! To calculate the grade he needs in the fifth subject, we'll have to do some math (or rather, clown math)!
Let's break it down, shall we? The first four subjects have grades of 55, 60, 65, and 65. When we add them all up, we get 245. Since there are five subjects in total, the "bo" needs a total of 65% average. In percentage terms, that's a whopping 325!
To find out the grade he needs on the fifth subject, we have to subtract the total he has already (245) from the desired total (325). So, 325 - 245 equals... 80!
So, to graduate like a boss, your "bo" needs to score an 80% on the fifth subject. I hope he's ready to hit the books and unleash his inner academic clown! Good luck to your friend!
To find out what grade the bo needs in the fifth subject to graduate, we first need to calculate the average of the first four grades.
Adding up the first four grades:
55 + 60 + 65 + 65 = 245
Now, divide the total by the number of grades (4) to get the average:
245 ÷ 4 = 61.25
So, the average of the first four subjects is 61.25.
To find out what grade the bo needs in the fifth subject to achieve an average of 65%, we can use the following formula:
(average × number of subjects) + desired grade = total marks
Let's plug in the values we know:
(61.25 × 5) + desired grade = total marks
Now, rearrange the formula to solve for the desired grade:
desired grade = (total marks) - (average × number of subjects)
desired grade = (65 × 5) - (61.25 × 5)
desired grade = 325 - 306.25
desired grade = 18.75
Therefore, the bo needs a grade of 18.75 in the fifth subject in order to graduate with an average of 65% in all five major subjects.
