An amusement park charges $28 to enter and $0.50 per ticket

(Solve)

Isn't the ticket the entrance fee?

oh well,

assuming that

each person paid 0.50 to enter

if a certain gropu paid 28 to enter, how many peple

total cost=costperperson times numbe rof person

28=0.5 times number of persons

divide by 0.5 or multiply both sides by 2 (same thing)

56=number of person
