Question

The surface area of an oil spill gets 125% larger every day, represented by the function s(x) = (1.25)x _ 1. On the first day, it covered an area of 49 square meters. Which function would be used to find the area of the oil spill on the 33rd day?

s(x) = (1.25)x _ 49

s(x) = (1.25)49 _ 1

s(x) = 49(1.25)x _ 1

s(x) = 1.25(49)x _ 1

Answer 1

The answer to this question would be C. s(x) = 49(1.25)x − 1

Answer 2

s(x) = 49(1.25)x − 1 is the answer because x would have to be with the precent and 49 was for the first day.
