You can put this solution on YOUR website!
depends what the exam is worth.if it is everything then you need to pass.
if it is 10% you are too late. Get ready for summer school.
you need to hope that it is most of he semester grade and that you can pass it.
45x+100y=65
45*.6+100*.40=67
if the final is worth 40% You can pass with a grade of 100 on the test
45*.2+70*.80>=65
if you get a 70 on the final and it is worth 80% you can pass.
