You have to put what kinda if properties you use to slice the problem
An acute angle is less than 90 degrees. An easy way to remember is that it's smaller, so it's cuter, meaning an aCUTE angle.
Given, there are an average of 150 citizens eat daile in the cafeteria.
The average price of their meals = $5.95.
The discount given for sinior citizens in their meals = 20%
So we have to find 20% of $5.95 first.
20% of $5.95 = 
= 
= 
= 
So, the amount of discount given to the senior citizens = $1.19 per head.
As there are 150 cinior citizens daily.
So total discount given daily = $
=$
So we have got the required answer.

Answer:274887.52
Step-by-step explanation:y= (a+1)^t
411/60= 6.85 hours
8900(1+.65)^6.85
274887.52
