$152 in 4 days. At that rate how many days will it take him to earn $532

One way to solve this is to set up and solve an equation of ratios:

 $152         $532
=
4 days           x
                                                2128
Then 152x = 4(532), and  x = = 14.  It'll take Seth 14 days to earn                                                                             $532.
