Question

an adult pass for an amusement park cost $2 more than a child's pass. when 378 adult and 214 children's passes were sold the total gate receipts were $2384. What is the cost of an adult ti

Answer 1

Let c = the cost of a child pass

 Let c + 2 = the cost of an adult pass

378(c+2) + 214c = 2384

378c + 756 + 214c = 2384

592c = 1628

c = $2.75

c+2 = $4.75
