Marlon had 30 female baby bunnies in his hutch. They matured after four months, and he gave 2/5 of them to his friend Rodney. If after another three months the bunnies conceived and gave birth to 2 kittens each, calculate the total number of bunnies Marlon has in his hutch now.
When he gave Rodney 2/5 of the bunnies, he gave away 2/5*30 = 
<gadget id="calculator">2/5*30</gadget>
<output>12</output>
12 bunnies.
He remained with 30-12 = 
<gadget id="calculator">30-12</gadget>
<output>18</output>
18 bunnies.
When the bunnies gave birth to two kittens each, the total number of kittens born is 18*2 = 
<gadget id="calculator">18*2</gadget>
<output>36</output>
36.
In total, Marlon now has 36+18 = 
<gadget id="calculator">36+18</gadget>
<output>54</output>
54 bunnies.
