A little brother, lacking rizz, has been taking money out of his sister's piggy bank each week, hoping she doesn't notice. If he takes a quarter, or $0.25, out of the piggy bank each week, how much will the piggy bank still have if the sister started with $27?

b) y = 27x + 0.25
c) y = -0.25x + 27
d) y = 0.25x + 27
c) y = -0.25x + 27
