Answer:
(a) -4 dollars
(b) +343 members
Step-by-step explanation:
(a) The change in the value of each share is the total amount of change divided by the number of shares:
change per share = (total change)/(number of shares)
change per share = (-40 dollars)/(10 shares) = -4 dollars/share
The change in value for each share was -4 dollars.

(b) As with most rate problems, the quantity is the product of rate and time.
growth = (7 members/week) × (49 weeks) = 7×49 members
growth = 343 members
The change in the club's size was +343 members.
