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.

Respuesta :

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