Answer:
16 tickets
Step-by-step explanation:
The entry fee ($4) is to be subtracted from the total that Heidi spent ($12). This leads to $8 left for spending on tickets.
Let the number of tickets Heidi purchased be x. Then:
$8.00 = ($.50/ticket)x.
Dividing both sides by $0.50,we get 16.
Heidi bought 16 ride tickets.
