Answer:
No. of ticket bought is 4
Step-by-step explanation:
Let the no. of ticket bought be x
Given cost of 1 ticket = $12
Therefore cost x ticket = x*cost of 1 ticket = x*$12 = $12x
parking fee = $5
given that it is flat so, whatever be the no. of ticket bought or family member,
the parking cost will remain $5 only.
Total money paid by family = parking charge + cost x ticket = 5+12x
But , given that family paid total of $53
then
5 + 12x = 53
=> 12x = 53-5 = 48
=> x = 48/12 = 4
Thus, no. of ticket bought is 4.
This can be validated as shown below
cost of 4 ticket as 12 each will be = 12*4 = 48
thus total money paid = $(48+5 )= $53
