If a bass has a length of x inches, where x is between 20 and 25 inches, its weight can be estimated by the formula w(x)=0.96x-14.4.
a)what length of bass weighs 6.8 pounds?
b)what lengths of bass weigh less than 6.8 pounds?
i dont even know where to

This question can be solved through the concepts of Algebra. We are given the range of the length of the bass which is from 20 to 25 inches therefore the answers must revolve around these values. Also, an expression for the weight of the bass is given. (this is with the assumption that x is in inches and W is in lbs)

a. Since we are asked for the length of the bass when the weight is equal to 6.8 lbs, therefore we substiture 6.8 to the equation

6.8 = 0.96x - 14.4

therefore x = 22.083 in

b. Since we are asked for the length of the bass when it weighs less than 6.8 lbs, the answer should be a range of values. Since the least value of x is 20, therefore the answer is

20 <= x < 22.083

<= less than or equal to
