Janet counts 30 crows on the powerlines and 60% more hawks than crows. How many birds does she count total?
First find how many more hawks than crows there are: 60% * 30 crows = 
<gadget id="calculator">60*.01*30</gadget>
<output>18</output>
18 crows.
Then add that number to the number of crows to find the total number of hawks: 18 crows + 30 crows = 
<gadget id="calculator">18+30</gadget>
<output>48</output>
48 crows.
Then add the number of crows to the number of hawks to find the total number of birds: 48 crows + 30 crows = 
<gadget id="calculator">48+30</gadget>
<output>78</output>
78 crows.
