Answer:
The Cold War led to spheres of influence and encouraged nations to ally themselves directly or tacitly, by accepting financial and military support, with either the NATO or the Warsaw Pact powers.
Explanation:
When the movies were $2.95 a month, she rented 10, meaning she spent $29.50 (2.95 * 10)
She then rented two fewer movies, meaning she rented 10-2 which equals 8, and spent $27.60 (3.45 * 8)
She then cut the number of movies rented in half 8/2 which equals 4, and spent $17.80 (4.45 * 4)
So she now rents 4 movies per month, and spends $17.80
Hope this helps!
