a) 245 members

b) 4 dollars

Step-by-step explanation:

a) If 7 new members were added each week, then after 35 weeks, the number of new members that would have been added =

7 members/week × 35 weeks = 245 members

Therefore the club's size changed (increased) by 245 members.

b) Number of shares owned by Mary from a certain stock = 7 shares

Decrease in the total value of her shares = 28 dollars

If 7 shares decreased by 28 dollars, then 1 share decreased by

28 ÷ 7 = 4 dollars

This means the value of each share changed (decreased) by 4 dollars.
