Answer:
0.6
Step-by-step explanation:
You are told the equation is [tex]y = kx[/tex]
You know the value of [tex]y[/tex] is 48 when [tex]x[/tex] is 80.
Therefore, we can substitute these answers into the equation:
[tex]48 = 80k[/tex]
This means that to solve for [tex]k[/tex], we must divide the 80 over:
[tex]k = \frac{48}{80} = \frac{6}{10} = \frac{3}{5} = 0.6[/tex]
Therefore, [tex]k = 0.6[/tex].
