Help with this question plz!

MJK is the similar as a triangle

cost for ordering n tickets online. = 16n+2.50

where n is the number of tickets ordered.

Step-by-step explanation:

Given that when purchasing tickets to a waterpark on internet

he has to pay 16 dollars per ticket and also an additional service cost of 2.50 dollars.

This 2.50 dollars is fixed irrespective of number of tickets he orders

Hence if n tickets are purchased online,

Ticket cost to be paid = 16(n) = 16n

One time service cost            = 2.50

Thus the cost for ordering n tickets online. =total cost

C= 16n+2.50

where C represents the cost, and n is the number of tickets ordered.

Here we substitute n=4, to get his particular  cost

C= 66.50 dollars
