$\textbf{Juan's Expanded Stamp Archive}$

Juan has expanded his stamp collection to include stamps from Mexico alongside his existing collection from Brazil and Peru. He organizes his stamps by country and by the decade they were issued. The prices he paid for them at a stamp shop were: Brazil and Mexico, $8$ cents each, and Peru $5$ cents each. Juan is speculating about the cost of his North and South American (excluding Mexico) stamp collections from the `60s and `70s. Compute the cost of these particular collections in dollars and cents.

In his collection:
- From the `60s: Brazil (7 stamps), Peru (4 stamps)
- From the `70s: Brazil (12 stamps), Peru (6 stamps)
