Pleas help wuickly with this question for studying for my math test

D - 320

Step-by-step explanation:

You divide 48 by 15% and it equals 320 which is the starting value. To check your answer you take 15% out of 320 which gives you 48. Letter C is incorrect because 15% of 150 is 22.5. A and B are not correct because A is lower than the amount spent and there is no way that B would work because 15% of 55.20 is 8.28. Good luck with your math test!
