Jeffery has grades of 93 and 81 on the first two tests of the quarter. Progress reports will go home after the third test.
If Jeffery does not have an A average on his progress report, he cannot go to the football game that week.
Jeffery will have to make at least what grade on the third test to be allowed to go to the football game?

f(x) = y

f(-3) = -5

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
