John attends a protest for 4 days. He then attends a second protest for 25% longer than the first. How many days did he spend protesting?
The second protest was 4*.25=
<<4*.25=1>>1 day longer than the first. So the second protest was 4+1=<<4+1=5>>5 days. Thus he spent 4+5=<<4+5=9>>9 days protesting. #### 9 Mary wants to bake 10 apple pies for a charity event. Each pie needs 8 apples and she already harvested 50 apples from the trees in her garden. How many more apples does she need to buy to make all 10 pies?

How many 4-pound rocks does Jack need to hold to make their weights equal?
