Question 344549
{{{TotalCost = CostOfRocks + CostOfTrees}}}
A ton of rocks costs $60 and you need 30 tons of rock. So {{{CostOFRocks = 60*30 = 1800}}}
{{{CostOfTrees = t * 84}}}
{{{TotalCost <= 2500}}}
{{{2500 <= 1800 + 84t}}}
{{{700 <= 84t}}}
{{{8.33 < t}}}
Since you can't buy less than a full tree, you can plant 8 or fewer tress and still be within the budget
