this year=x

next year=1.115x

difference btwn next and this year=1.115x-x, which equals 0.115x

0.115m

Step-by-step explanation:

A number going up by 11.5% means multiplying that number by 1.115. If the price for the first year is m, and the price for the next year is 1.115m, then the difference between the two is 1.115m-m=0.115m. Hope this helps!

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.
