Answer

This is a Matrix question.

   Ahmad  Betty  Cai Yun   Muthu  Total 
Plan     5u – 15 5u – 15 5u – 15 5u – 15 20u – 60
Actual  17 7u   5u – 15 12u + 2 

20u – 60 = 12u + 2

20u – 12u = 2 + 60

8u = 62

4u = 62 ÷ 2 = 31

12u = 31 × 3 = 93

93 + 2 = $95

Yes, 12 units = $93  is correct and the answer is $93 + $2 = $95. In addition, I would advise you to add 2 $ signs as shown below :

 1u=$7.75
12u =$9.
