Question

The student has received scores of 85, 88, 87, and 90 on their algebra test. What is the minimum score they must earn on the fifth test to have an overall average score of 87?

Answer 1

answer: 85

(85 + 88 + 87 + 90 + x)/5 = 87

85 + 88 + 87 + 90 + x = 5 * 87 = 435

350 + x = 435

x = 435 - 350

x = 85
