In order for brady to earn a b in his biology course, his test scores must average at least 80%. on the first 5 tests, he has an average of 77%. there is one test remaining in the course. what is the minimum score brady needs to earn on the last test to score a b in the class?

answer: the answer is 35%

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
