Subtracting a negative means to add, so we have

Answer:
the answer is option B because it has been factorized completely
Answer:
There is a 4% decrease
Step-by-Step:
if the previous total was 50, then each animal represents 2%. 50*2=100. if you are increasing the dogs by 20% of 20, then you are increasing them by 4 equaling out to 24 dogs. If your decreasing the cats by 20% of 30, then you are decreasing them by 6 equaling out to 24 cats. The new total of animals is now 48. Seeing how each animal still represent 2%, the new percentage is 96%. Subtracting the previous percentage from the new percentage gives a 4% difference.
50 * 2 = 100%
20 * 1.2 = 24
20 * .8 = 24
24 + 24 = 48
48 * 2 = 96%
100% - 96% = 4%
It’s B bc $2.50 divides by 10 is $0.25 and that means you take $0.25 and times it by 18 and get the price
