Q:
# Sherman hopes to get at least a 90 average on his science test. He has one more test before the end of the year. His past test scores are 79, 94, 91, and 92.Write and solve an inequality that represents the situation. What is the lowest score Sherman can get on his final test and reach his? show your work

Accepted Solution

A:

(79 + 94 + 91 + 92 + x) / 5 > = 90

(356 + x) / 5 > = 90

356 + x > = 90 * 5

356 + x > = 450

x > = 450 - 356

x > = 94 <=== Sherman can get the lowest score at 94

(356 + x) / 5 > = 90

356 + x > = 90 * 5

356 + x > = 450

x > = 450 - 356

x > = 94 <=== Sherman can get the lowest score at 94
