Ineed to know this problem by tomorrow can someone me out i'm stupid

16 a, b, c, d, and 17 a, b

I can solve for 16, but I'm too tired (read: lazy) to do 17 at the moment. Hope this helps some at least...

Step-by-step explanation:

16:

A. x + y = 230.

x= single scoop cones, y= double scoop cones.

In the word problem, we are told that they sold 230 cones in one day. Thus, you get 230= x+y.

With 2x+2.5y=498 this represents the price of the cones plus how much they earned.

$2+$2.50=$498.

B . I already kinda answered this up above, but x= the single scoop cones, and y = the double scoop cones.

C. y= -0.8x + 199.2

D. not too sure what they're asking for here (maybe I'm just too tired right now and therefore my last two brain cells are giving out-- it's 12 am where I am rn), but I'll try my best in the way I interpreted the question.

So, this may be wrong! BUT here we go--

The collective sales from 230 cones is precisely $498.

21.4 i did it already for s1

step-by-step explanation:

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.
