D will be your answer because to get how many pickles in all you need to multiply the pickles by how many hamburgers
0.30 is the same as 3/10 so then you would add 3/10 and 4/10 which equals 7/10 which then gives you with 3/10 ice cream left
First you want to put 8 over x = 4 over 6
8/x =4/6
Then you will cross multiply 8 to 6 and 4 to x
48=4x
then divide 4 to both sides and you get 12
YOUR ANSWER IS 12
