I think this is trying to represent the degrees of a pie chart.
To find the degree of the pi chart per person you need to 72/12=6
Than to find the amount of degrees per subject multiply 6*amount of students.
Example:
So allison spent 3/5 meaning she saved 2/5 because 3/5 + 2/5 = 5/5
change the 2/5 into decimals by 2 ÷ 5 = 0.4
multiply $55 with 0.4
55 x 0.4 = 22
so she ends up saving $22
