The county fair charges $1.25 per ticket for the rides. Jermaine bought 25 tickets for the rides and spent a total of $43.75 at the fair. Jermaine spent his money only on ride tickets and fair admission. The price of the fair admission is the same for everyone. Use y to represent the total cost and x to represent the number of ride tickets.

x = 25 tickets
y = 43.75 - Total cost
a = admission cost
$1.25*25 + a = $43.75
$31.25 + a     = $43.75    subtract $31.25 from both sides
a = $43.75 - $31.25 = $12.50 - cost of admission.
$12.50 + $31.25 = $43.75 - Total cost at the country fair.
