a scientist has two solutions, which she has labeled solutions a and solution b. each contains salt. she knows that solution a is 55% salt and solution b is 80% salt. she wants to obtain 180 ounces of a mixture that is 60% salt. how many ounces of each solution should she use?

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 !
