Question 1062480: suppose your class in raising money for their field trip. You make $5 on each smoothie and $3 on each soft pretzel that you sell. Let x represent the number of smoothies sold and y represent the number of soft pretzels sold. How many items of each type must you sell to raise money more than $150

You can put this solution on YOUR website!
x, number of smoothies
y, number of pretzels
5x%2B3y=150-----only whole numbers are allowed for x and y.

y=-%285%2F3%29x%2B50


More practically, MORE than $150 is wanted.
5x%2B3y%3E150


graph%28400%2C400%2C-3%2C55%2C-3%2C55%2C-%285%2F3%29x%2B50%29
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.
