Answer:
A. They will pay more with the new price plan.
B. The new price plan would be cheaper.
Step-by-step explanation:
A. They will pay more with the new price plan.
For the current price plan, you would add the $3 rent to the two games (which are $4 each). This basically means: 
$3 + $4 + $4 = $11
For the new price plan, you would add the $11 rent to the two games (which are $2 each). This basically means: 
$11 + $2 + $2 = $15
Therefore, you pay more for the new price plan.
B. Using similar logic as part A, the current price plan 7 games would cost:
$3 + [7 x ($4)] = $31     (multiply by 7 since they play 7 games)
 For the newprice plan, 7 games would cost:
$11 +  [7 x ($2)] = $25    (multiply by 7 since they play 7 games)
Therefore, the new price plan would be cheaper.
Hope this helps :)
