Answer:
More practically, MORE than $150 is wanted so the answer is 3x-x+2=4
Explanation:
Any choice of WHOLE NUMBER divisible by 3 will work for x to give a whole number for y, for acceptable points ON the line; but points found ABOVE the line with whole number coordinates would also be acceptable for this INEQUALITY problem. As example, do you understand that x=27, y=11, will work? It is just one of many, many possible solutions.
