Today, everything at a store is on sale. The store offers a 20% discount. The regular price of a T-shirt is $18. What is the discount price?
If the regular price of an item is dollars, what is the discount price in dollars?

14.4 dollars

Step-by-step explanation:

20 percent of 18 is 3.6 and 18-3.6 is 14.4 which therefore is the discount price.

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

i hope this !
