You can put this solution on YOUR website!
x, how much grapes
y, how much cherries

Best to account for cost using both fruit quanties, pounds, as variables.
%282x%2B1.5y%29=9%2A5

Do what you want with the form,
2x%2B%283%2F2%29y=45

%283%2F2%29y=-2x%2B45
y=-2x%282%2F3%29%2B%282%2F3%2945
y=-%284%2F3%29x%2B30
