A study analyzed the average yearly salt intake in the United States from 2012 thru 2017. The data is summarized in the table: Year Annual Salt Intake
(grams)
2012 3,618
2013 3,646
2014 3,680
2015 3,716
2016 3,751
2017 3,790

The study found that the data after the year 2012 can be modeled by the function f(x) = 36.4x + 3,608, where x is the number of years since 2012 and f(x) is the total amount of salt ingested in grams. Describe the significance of 3,608. (4 points)
The average amount of salt in grams used in 2013

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
