Ryan's average for 5 arithmetic test was 89. On four of the tests he made 96,86,92, and 80. What did he make on the fifth test?

Answer 1

(96 + 86 + 92 + 80 + x) / 5 = 89

Solve x?

Answer 2

89=(93 + 86+ 92+ 80+ x) / 5

Solve for 89 x 5 = 445
Add other grades 93+86+92+80=351
445-351=x
x = 94

Answer 3

94 is correct. Karen -- I like your method for solving this problem.
