Question 1062480
x, number of smoothies
y, number of pretzels
{{{5x+3y=150}}}-----only whole numbers are allowed for x and y.


{{{y=-(5/3)x+50}}}



More practically, MORE than $150 is wanted.
{{{5x+3y>150}}}



{{{graph(400,400,-3,55,-3,55,-(5/3)x+50)}}}
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.
