Hi,
first four tests, the scores were 75, 90, 73, and 75.
What is the lowest score that the student can get on the last test and still get a B?
to get a B in math,a student must score an average of 80 on five tests.
(75+90+73+75+ )/5 ≥ 80
75+90+73+75+x ≥ 400
313 + x ≥ 400
x ≥ 87
87 the lowest score that the student can get and still get a B
