If the student got 123 marks and failed by 39, your first step would be to add the two together, getting 162. This is the amount of marks needed to pass the test.
You would then divide 162 by .36 (.36 is equivalent to 36%). This would result in a maximum of 450 marks.
The maximum marks on this test are 450 marks.
Oh! thats Easy, just put a one under the 30 and the flip it and then divide and u should get your answer
Answer:
n = 30....................
m = amount of money you receive
You need at least $40, so that means you need m = 40 or more
So 
which is the same as saying 
. You flip both sides and also flip the inequality sign as well.
At the same time, your parents won't give you more than $50. So the largest m can get is m = 50. This means 
-----------------
Combine and to get the compound inequality 
This represents all the possible values of m. We see that m can get as small as m = 40, or as large as m = 50, or anything in between.

Answer:
B
but i have to write more to let me post this so here it is
