. Noriko's final mark for her Financial Mathematics course was based on four tests with different weightings. Test one counted for 10% of the final grade, test two for 20%, test three for 30% and test four for 40%. If Clara received 70% on test one, 85% on test two, 64% on test three and 72% on test four, calculate her final mark.

hey Mate
Step-by-step explanation:
Right now, you have 100% of the Homework 25%. That means you have 100% of those 25 points, or 25 total homework points.
Right now, you have (100+88+86+79+76+76+74)/700 = 579/700 = 0.827 = 82.7% of the Tests 60%. That means you have 82.7% of those 60 points, or 60(.827) = 49.63 total test points.
You could have a total of 25+60 = 85 points so far. You have (25+49.63)/85 = 0.878 = 87.8% of those points. That means, right now, your grade is 87.8.
I'm going to assume that a 90 is an A, though many schools do it differently. Right now, you've got 25+49.63 = 74.63 points. To get to 90, you need 90 - 74.63 = 15.37 points. The final is worth 15%, which can only give you a total of 15 points. So, even if you get a 100 on your final, you'll have a grade of 89.63. If your school rounds up, that would be an A.
Bottom line is, you've got a solid B or B+ right now. To get an A, you'll need a perfect score on your final.
Answer:
18x/25
Step-by-step explanation:
let the total final grade be 'x'
10% of 'x'=x/10
20%of'x'=x/5
30%of 'x'=3x/10
40%of 'x'=2x/5
x/10+x/5+3x/10+2x/5= x
70% of x/10=7x/100
85% of x/5=17x/100
64% of 3x/100=96x/500
72% of 2x/5=72x/250
Therefore, Normika's Final mark= 7x/100 + 17x/100 +96x/500 + 72x/250
=18x/25
72/100
