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

Hope this helped❤️
