Each ticket costs $1.25
Jermaine bought 25 of them, which costs 25 x 1.25
25 x 1.25 = 31.25
He spent a total of $43.75 from the tickets and price of admission
we know the tickets cost 31.25, so the admission cost was 43.75 - 31.25
43.75 - 31.25 = $12.5
b) y = 1.25x + 12.5
Where y is the total cost, 1.25 is the price of each ticket, x is how many tickets a person bought, and 12.5 is the admission fee.
Hope it helps :)
