Question

Peter begins his kindergarten year able to spell 10 words. He is going to learn to spell 2 new words every day. Determine the minimum number of whole days it will take for him to be able to spell at least 75 words.

Answer 1

It will take Peter a minimum of 33 whole days before he is ab
le to spell 75 words......I think.

Answer 2

You start of with 65 (deduct 10 from 75 as he already knows 10) then divide it by two. This give you 32.5 rounded to 33.

Hope this helped :D
