First we need to calculate 25% of 120. If 120=100% and X=25% then 120•25=100•X 3000=100X X=30. Now we know that 25% of 120 is 30. Now we need to calculate 40% of 120. If 120=100% and y=40%, then 120•40=100y 4800=100y y=48. Now we know that 40% of 120 is 48. To find out how many more questions had Riley finished then Annabel, we need to subtract 48 with 30 48-30=18 FINAL ANSWER—18
