I received my tickets off an internet site with a discount of 28%. The online sales company then put a 12.5% service fee on my ticket. What percentage of the original price did I get the tickets for?

81%.

Step-by-step explanation:

Let the original price be  x.

With a discount that made it x - 0.28x = 0.72x.

Then we add the service fee of 12.5%:

= 0.72x + 0.125*0.72x

= 0.81x.

So it's 81%.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3
