Answer: 15856
Step-by-step explanation: 166786.9963 - 150930.6256
= 15856.3707
= $15856
<span>the number of trees in the garden = x
</span><span>coconut trees = 0.6x
</span><span>mango trees = 0.6x * 0.25 = 0.15x
</span><span>apple trees = 0.15x * 0.2 = 0.03x
0.03x = 1500
x = 1500/0.03
x = 50 000 </span>← <span>the number of trees in the garden.</span>
