Restrict Membership Payments to Fixed Contribution Amounts in 4.7
The screenshots don't match the settings you listed above (e.g. "Additional Payment" is set to "Yes") but assuming the question is, "How can I match the 4.7 screen to the 4.0 screen?" you can add a Price Set for Memberships.


Go to Memberships menu » New Price Set.
Fill in the required fields.  Used For should be set to Membership.
On the New Price Field screen, set the Input Field Type to Radio.
Create as many options as needed, setting the "Membership Type" to the "A" Membership.
Go to the contribution page in question's Membership tab.  
Set the Membership Price Set to the set you just created and save.
