Carlos took a test and made a 50. On the next test, he made 75. What is the percentage of change between the two test scores? A. 150% increase
B. 150% decrease
C. 50% decrease
D. 50% increase

D

because if you increase by 50%, you get half of 50, which is added on ecause its an increase, therefore you should be left with 75%
