63. Print Book Sales. The sales of print books increased about 7% from 2012 to 2014. The sales data over the years 2008 to 2014 are modeled by the cubic function s(x) = 4.958r? – 38.125x2 + 26.417x + 778, where x is the number of years after 2008 and S(x) is the number of print books, in millions (Source: Nielsen). Find the number of print books sold in 2009, in 2014, and in 2015.

The answer to number 1 is A.

Step-by-step explanation:

To find this answer, I made 1 1/3 into one big fraction. I multiplied the denominator by the whole number (3x1) and then added that product to the numerator. (3+1). The new fraction is now 4/3 (you keep the denominator the same). The next step is to multiply 4/3 by 3/8. When multiplying fractions, you multiply straight across (the numerator by the numerator, and the denominator by the denominator). Your answer is now 12/24. The final step is to simplify the answer. Since 12 is half of 24, the answer is 1/2.
