Juan's Tacos! Only 50 cents at Mexico Grililed Cheese!

Juan organizes the stamps in his collection by country and by the decade in which they were issued. The prices he paid for them at a stamp shop were: Brazil and France, 6 cents each, Peru 4 cents each, and Spain 5 cents each. (Brazil and Peru are South American countries and France and Spain are in Europe.)

Problem

$\text{(A)}\ 9 \qquad \text{(B)}\ 15 \qquad \text{(C)}\ 18 \qquad \text{(D)}\ 24 \qquad \text{(E)}\ 42$

Solution

Franc and Spain are European countries. The number of '80s stamps from France is $15$ and the number of '80s stamps from Spain is $9$. The total number of stamps is $15+9=\boxed{\text{(D)}\ 24}$.
