Step-by-step explanation:

if you notice here Josiah starts with 250 and Katie starts with 215, and in Josiah's equation he saves 25$ each month while Katie save 45$ each month, in order to find our answer we must multiply there starting amount by how many months.

A: 4 months is incorrect because Katie has 45x4+215 is 335, and Josiah has 25x4+250 is 350, so Katie is still behind

B: 5 months is incorrect because Katie has 45x5+215 is 375, and Josiah has, 25x5+250 which is 375, so they have the same amount of savings

C: 6 months is correct  because Katie has 45x6+215 is 420, and Josiah has, 25x5+250 which is 400 , so Katie has more savings, Thus C is correct
