Select the equation that most accurately depicts the word problem. A 3-pound tub of butter at n dollars per pound costs $3.85.

3n = 3.85
3 + n = 3.85
3 - n = 3.85
= 3.85

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
