You can put this solution on YOUR website!
m = price for Mangos, in unit of dollars per mango
d = price for durians, dollars per durian
-
6*m=2*d, description of costs
simplified to 3%2Am=d


PURCHASE

3%2Am%2B4%2Ad=30

3m%2B4%283m%29=30
3m%2B12m=30
15m=30
m=30%2F15
highlight%28m=2%29--------------This is $2 per Mango.
