Answer is B. 4,096
I encountered this problem before. This is a trick question.
84 is not really the number 84. It is 8 raised to the 4th power.
So 8⁴ is equal to 4,096.
8 x 8 x 8 x 8 = 4,096
8 x 8 = 64
64 x 8 = 512
512 x 8 = 4,096
The answer is 7,069.92. You can get this by substituting the known values into the given equation, or I = 22660*13%*2.4. Then, multiply. Make sure to convert 13% to a decimal by moving the decimal point 2 places to the left, which will give you 0.13.
we will draw the graph according to the given constraints
NOTE: when we draw the graph from constraints inequalities becomes equalities just to draw the graph
Given constraints are:




Now we draw the graph of given constraints using graphing calculator. Please see the attachment for the graph. Shaded region is the feasible region
1. I did 9x8 since you usually work 8 hours a day but did not give answer, so I add or subtracted 0.5 to 8.
2. i did 9*7.5=67.5 , keep in mind that he worked for 11 hrs that day so 11-7.5=3.5 hours left
3. then I subtracted 67.5 from 114.75 and got 47.25
4. I divided 3.5 by 47.25 and got 13.5
