suppose that y varies directly as x and y = 47 when z=329

Question

suppose that y varies directly as x and y = 47 when z=329

Answer 1

possibly you meant x not z

in the problem

y = kx for direct variation

if

y = 47 when x = 329 then

47 = 329k

k = 47/329 =1/7 = the constant of proportionality

y = x/7
