Mrs. Daniels, an English teacher, is having her students track the number of words they read in a book. She took their data and created the graph below. What is the rate of words per page?
A.
250 words per page
B.
200 words per page
C.
400 words per page

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
