Question

Solve this problem.
A student needs at least 80% of all points on the tests in a class to get a B. There are three 100-point tests and a 250-point final. The student's test scores are 72%, 85% and 78% for the 100 point tests. What is the least score the student can make on the final and still get a B?

Answer 1

Let x represent the % score on the last test.

student needs at least 80% of all points on the tests in a class to get a B



235 + x = 320

x = 320-235 = 85

x = 85% Student needs an 85% on the last test

250 Question Test

.85*250 = 212.5
