Step-by-step explanation:

Step 1: State what is known

They tell us that 3 pounds cost 4.50$

Step 2: Find how much 1 pound cost

We divide 4.50$ by 3 to find out how much 1 pound costs

4.5/3 = 1.5

Therefore 1 pound of sour candies cost 1.50$

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
