$\textbf{Linda's Vintage Postcards}$

Linda organizes the postcards in her collection by country and by the decade in which they were issued. The prices she paid for them at a shop were: Germany and Italy, $7$ cents each, Canada $5$ cents each, and Mexico $6$ cents each. (Germany and Italy are European countries and Canada and Mexico are in North America.) In Linda's collection arranged by decades and countries, she owns:
- 1950s: Germany 5, Italy 9, Canada 8, Mexico 7
- 1960s: Germany 6, Italy 8, Canada 10, Mexico 8
- 1970s: Germany 9, Italy 10, Canada 12, Mexico 11

In dollars and cents, how much did her European postcards issued before the $70\text{'s}$ cost her?
