the inequality would be 29.99+0.18x≤34 because 29.99 is the constant. and the 0.18 is the 'slope' if this were being graphed. and it and it can be equal to but no more than $34.
you subtract 29.99 from both sides
0.18x=4.01
divide by 0.18
x≤22.28
but you cant send a partial text so it rounds down to 22
This question is very big, you should shorten your question a bit so that I can answer it quickly, the rest is just that I did not understand the question a bit
