# Maths question help please watch

1. The average of all the grades on an algebra test was 90. If the average of the 8 males' grades were 87 and the average of the females grades were 92. How many females took the test?
a) 8 b) 9 c)10 d) 11 e) 12
2. When you do these you need to think about it how you would in a normal scenario and form a basic equation
3. or each male was 3 marks below average and there were 8 so that totals 24

each female is 2 above average so to get the 24 marks needed means you need 12 girls.
4. Thank you very much!
