**Damon**, Sunday, July 20, 2008 at 3:48pmr = tons of rock

t = number of trees

r≥30 to cover yard

c = 60 r + 84 t ≤2500

if I use the minimum amount of rock (30 tons) then I can use the maximum number of trees so

r = 30

60 * 30 + 84 t ≤ 2500

1800 + 84 t ≤ 2500

84 t ≤ 700

t ≤ 8

so 5 trees is a solution
