Adrian took $42.50 to the fair. each ticket at the fair cost t dollars. adrian bought 5
tickets. which expression represents the amount of money, in dollars, that adrian had after he bought
the tickets.
a. 42.50 – (5-t)
b. 42.50 – 5
c. 42.50(5) – t
d. 42.50 – 5t

D. 42.50 - T

Step-by-step explanation:

Well, each of the tickets cost $T. So, he bought 5 tickets, so that makes the ticket dollars, 5T. Now, you have to subtract 5T from $42.50.

So, $42.50 - 5T.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
