I got my and as 91 but it is wrong
p: 1 u
c: 3 u
cost
p: 31 u
c: 45 u
total = 76 u
1/4 = 76 u
remaining money = 3/4
3/4 of remaining = 9/16
so
9/16 = 76 u x 3 x 3/4 = 171 u
total no. of calculators bought
= 15 + 171/3 = 72

¾ x ¾ = 9/16 , so in your last equation you should be finding 9/16 x instead of ¾ x
