Question

Candace had scores of 93, 84, 92, and 85 on her first four exams of the semester. What score must she obtain on the fifth exam to have an average of 90 or better for the five exams?

Answer 1

93+84+92+85+x >=90

5

(Sorry make the greater than or equal sign so did >= )

354+x >=90

5

Multiply both sides by 5

354+x>=450

Subtract both sides by 354

x>=96
