One edition of alice’s adventures in wonderland has 352 pages. how many 4’s were used in its page numbers

There are 75 4s from page 1 to page 352. You do this by figuring out that there's one four from 1 - 100 in each 10. 4,14,24,34,44,54,64,74,84,94 so in each 100, there are 10. 10 x 3 (the three 100s in 300) = 30 4s. then you have to remember that there are 10 4s in each of the 40s too, so you add each of the 40s from each 100. 30 + (10x3) = 60 4s. Then you have to add the 4s from page 300 to page 352 still, so, 304,314,324,334,344 so that's 5 more 4s. 60 + 5 = 65 then you add the 40s row from the 300s. That makes 10 more 4s. So 65+10 = 75. Hope I helped! :)

The answer would be 484

The percent increase is 25%
