Question

sherman hopes to get atleast a 90 average on his science tests. he has one more test before the end of the school year . his past test scores are 79,94,91, and 92. write and solve an inequality that represents this situation. what is the powest score sherman can get on his final test and reach his goal ? show your work

Answer 1

That mean's in total there are 5 tests
5*90 =450 so his total score on the 5 tests should be greater then or equal then 450.
79+94+91+92
356
Let's say x= the last test score
356+x>=450
subtract 356 from both sides
x>=94
The lowest score Sherman can get on his final test is 94.
