Katie reads 157 pages of her book during the week and 164 pages over the weekend. How many pages does Katie read in all? (1 point)

Katie reads 157 pages during the week and 164 pages over the weekend. To find the total number of pages she reads in all, we add the two amounts:

157 + 164 = <<157+164=321>>321.

Therefore, Katie reads 321 pages in all.

The sum of the tens is 6 + 4 = <<6+4=10>>10.
