a)

Step 1: suppose advin had x dollars at first.

Step 2: make suitable equations that represents the actual scenario.

Step 3: find the value of x.

b)

Total amount left= $44.

Total amount spent on books= $28+2/5 of his initial money.

Suppose advin had $x initially.

then, initial money= money left+ money spent

therefore, x=44+(28+(2/5)x )

x= 72+2x/5

x-2x/5 = 72

(5x-2x)/5 = 72

3x/5 = 72

x=72(5/3)

x= 120

Therefore, Advin had total $120 at first.
