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!
