14 lb for $2.99 round to the nearest hundredth

Find the number in the hundredth place 9 and look one place to the right for the rounding digit 0. Round up if this number is greater than or equal to 5  and round down if it is less than 5.

= 0

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 !
