What expression, in simplest form, shows the value of the new area of the poster?
10(17 - r) = (170 - 10r) square inches

What expression shows the value of the planned area of the card?
The planned area of the card is the difference between the initial area of poster and the new area of poster.
i.e. (10 x 17) - (170 - 10r) = 170 - 170 + 10r = 10r square inches.
