I need help.

someone help please!

Step-by-step explanation:

The rule governing the number of magazines sold varies directly with the constant of proportion 10:

10 times the number of students comes out to 100:  10(10) = 100

25 times the number of students comes out to 250:  10(25) = 250

and so on.

In summary:  the number of magazines sold is y = 10x, where x is the number of students involved.

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.  

probably the last option
